The car runs good when it is cold, but when it gets warmed up you will be driving and it starts cutting out like it is not getting gas.

This could be a fuel pump cutting out but I want to clarify if the engine is completely cutting off when it get warm? If this is then it could also be a crank sensor.

Here is the guide to test the fuel pressure. I would suggest just hooking up a gauge and taping it to the windshield so you can see it when driving.

I attached the info about the crank sensor as well.

Or if I'm going up a hill the check engine light came on. Sometimes when I'm driving 60 it runs smooth but I feel a little bit of hesitation. Other than the second gear chug it is great.

Hello,

It sounds like the engine is misfiring under load which is typical. Here are two guides to help us fix the problem

Why does my car keep throwing cylinder 1 misfire code or what could be the problem making it do this?

This could be anything best to have a local professional freeze frame and record it to see if it is a sensor gone bad. otherwise you will dump a bunch of money on probably good parts. You can check the fuel pressure and compression to see if that is it. auto parts rent the fuel pressure gauge

At low idle, the car chugs and has no horsepower, and sometimes miss fires. We have changed the spark plugs many times and even with really expensive plugs with a five year warranty they died with in three months. What could be causing our car to burn though spark plugs. And how much will it cost to fix?

Are they completely black or are the electrodes burned off? If it is black the engine is too rich. Check the MAP, TPS and CTS sensors for proper functioning.
