Full list:
Ignition control module.
Coil packs.
Fuel filter.
Air filter.
Purge solenoid.
Throttle position sensor.
Mass air flow sensor.
Throttle body.

CarPros suggested:
G111 ground being loose(found with exposed wire, not sure if repair correctly).
Replace positive battery cable(have not done yet).

Other people suggest:
Camshaft sensor(have not done yet).

Car still stalls after driving for an amount of time, it starts right back up but stalls immediately, if left sitting for about an hour will run again without stalling.

I will say when we purchased the car there may have been a wire short behind the radio that would affect the speakers but not sure if that is related.

I saw no rust or greenish color it was bright fresh looking copper. How do we even change the G111 cable? We was going to splice it and remend it together but it looked very well intact so we just taped it with electrical tape.

Sometimes it is not the sensor or module that is bad. It may be a wire that is bad on that sensor/module circuit so just replacing any sensor/module, scan again for codes and see if the related code is still there or came back and if the sensor/module was already replaced, then 99% of the time it is a wire that is bad, or a loose connection or rust inside the insulation of a wire or a loose rusted ground.
Let me know what codes you have after a ten minute test drive and if the engine stalls, stumbles, lacks power, etc, and the readings from all testers that you can get your hands on like I mentioned before.
You can check if even that ground cable is bad by checking the voltage drop on both ends.
To do so, hook the negative voltmeter test lead to the negative battery post and the positive voltmeter test lead on the end of that ground where is bolts to G111 and make sure the test lead touches the exposed copper wire strands or the connection on the end of that cable, in other words not the attaching nut or bolt. Now, start the engine and read the voltmeter, it should read 0.1 volts or less. If it reads anything, that is the amount of voltage drop across that ground circuit from that spot where the positive test lead is to the battery negative post because the voltmeter has less resistance to ground and whatever voltage that is lost across that circuit the voltmeter will pickup and display as a voltage drop.
Now move just the positive voltmeter test lead to the other end of that g111 circuit and do the test again. If that cable branches out to several parts, just find the end of that wire/cable to whichever part be it sensor or module that you still have a code for and check that ground wire/cable. So attach the positive test lead on any ground wire/cable end you want to test as close to the part as possible to recheck the ground voltage drop. It should read no more than 0.1 volts more than your other test, so 0.2 volts, anything well over that is the amount of voltage drop just on that ground wire/cable so if it reads, let's say 4 volts, you are loosing 4 volts along that cable/wire and could well be rust inside the insulation that ruined the copper wire strands or a mouse or small creature has chewed up the wire.

No codes, when the dealer had the car they checked all wire connectors for rust etc. I will have the codes checked again to make sure none are present still. We had taken it to another mechanic that said he does not know what it could be and to maybe put a new PCM on the the car. The car has to be driven for about an hour before it stalls now then it will stall repeatedly every minute or five minutes or so. And I will see about getting a hold of some equipment to test it.

First thing is stop replacing parts, if need be save the money on buying an expensive pcm, instead purchase an Actron pocket code reader for $35.00. So you do not have to chance stalling while going to codes read by someone else.
Here are some: https://goo.gl/QE3hXh

So a voltmeter and a code reader is a good investment since we work on all of our cars ourselves? What other tool do you suggest that could help me trouble shoot this problem myself?

We bought pocket code reader and the car has absolutely no codes. We had bought the car and only been driving it for three weeks before this issue started. They only symptom the car had was that the battery was dead originally when we looked at the car. We test drove it three different times before making a decision on it. Originally when it started stalling the symptoms were different. That main wiring harness of the car could be moved or touched and it would cause the car to cut off and even when it was not being touch the car would cut off. If was causing the box with the fuse to make and electrical popping sound. We took it to the dealer and after the original $75.00 they needed more money so it cost us $400.00 for them to say its the ignition control module, we changed that ourselves due to them saying it would cost a total of $998.00. After changing that it drove for a day with not problem then cut off again. We had it checked for codes and the codes were for mass airflow, purge solenoid, throttle position sensor. So we replaced all of those. The car no stalls and cuts off after driving for an hour or so. It drives so smooth, blows good A/C. We do not have good reliable competent mechanics in our area. Even the dealerships do not care. My Husband is ready to give up on the car and sell he is frustrated. We do not feel knowledgeable with trying to chase a wire problem down. I have a question can a wire connected or behind the stereo be causing these problems? We have almost replaced everything that other people had the same problem and symptoms except the crankshaft/camshaft sensor and the PCM, You Guys have been a great help and any feedback, or suggestions to my questions I appreciate because I am not ready to give up, thanks hope to hear from you soon.

Did anyone replace that harness that when it is moved you hear popping in the fuse box?
Has it stalled after purchasing your code reader? It might not have codes as long as it is running fine, but if it stalls again, it should store a code. Maybe someone erased them. Anyhow the next time it stalls see if there are any codes, and remember disconnecting the battery might erase all the codes, too.

No, the harness was not replaced. They said it was from the ignition control module making it react like that and the fuse box was not seated properly. Is what the dealer said, and I am checking with my husband if he unplugged the battery since we drove it last.

Ask him if wiggling them same wires as before causes it to stumble, stall or make any popping noises, too.

It does not, before we changed the ignition control module and coil packs it was not doing it anymore after the dealership re-seated everything, since the mass air flow sensor and all that stuff that the codes showed up the car runs and drives very smooth not rough at all. When it starts it does hesitate a little but other than that it is running great until it stalls then it stalls multiple times and once it sits for an hour it runs smooth again. This has been an issue we have been trying to figure out for some months now. He said we did not disconnect the battery at all, I was not sure because we was looking at the wiring around the battery because you had suggested replacing the positive battery cable. The car only has 97,000 miles on it, we bought it for $2,500.00 and have sunk about another $1,000.00 or so into it.

You might want to see if the code reader will work while driving around, if so keep it plugged in until you find the problem. You may have to disconnect it when you exit the vehicle, but also add a fuel pressure gauge that you can watch and a ignition timing light just to see if you are loosing spark when it stall and/or a tachometer and watch it. Hook up a vacuum gauge too and a voltmeter up to first the fuel injector powered wire and/or the ignition to see if you are losing voltage from the ignition switch. When it stalls of course!

I was asking about the camshaft sensor earlier, I meant the crankshaft sensor? Also, when we installed the ignition control module we did not use the dielectric grease. We have both been working a lot and not had time to run those tests you recommended. I just had a thought that I wanted to share.

If the ignition control module came with the dielectric grease than you should use it. It helps dissipate heat and helps to prevent the module from burning up.

I am still trying to find the problem with my car. I replaced the crankshaft sensor and the car is still cutting off. It is like the key is being turned off after about an hour of driving, and it starts right back up, but will stall again. I also noticed that sometimes it will cut off and lose power for a second and regain power on its own without even starting the car. I think it may be the ignition switch. However, I have another question. I feel as if it has been a chain reaction type of situation, could the ignition switch be the root to all the issues or is it another issue and the ignition switch is now just the next part to get "burnt up"? Fist it was ignition control module, also replace coil packs at the same time, then we replace MAF, purge solenoid, throttle body, throttle position sensor, air filter, fuel filter, now crankshaft sensor after testing it with a voltmeter and a new battery. My husband did install an aftermarket radio, however I am not sure that is connected. What could cause part after part from going bad? The car runs and drive so smooth and lovely and then will just cut off, it could be the ignition switch, but what are the chances of us fixing that and it still cutting off? Our next route of action is going to be replace plugs and wires, ignition switch and the positive battery cable as well as the ground cable from the battery that branches to the trans-axle stud do the the end having a slight greenish blue look to it. I am about to loose my cool. Please help.

To me it sounds like the engine main relay is overheating and shutting off. Here is a guide and the location of the relay so you can run a test and replace the relay:

Check out the diagrams (below). Please let us know what happens.
