Still shutting off while driving

My car will shut off when driven awhile and later starts up when it sits for a short period. Can I get money back even though its been only two weeks and I bough it as is

There is no check engine light, but last time I had to jump it to get it running because something was draining the battery and I had to tap the fuel pump to get it running

Today when I drove on the free way at about 75mph, engine rpm was about 2200rpm. The engine suddenly shut off, at first the engine rpm shaked between 1000-1500 rpm for 1-2 seconds, then shut down to zero.

It happened last Dec. When I drove on the free way, exactly the same way. But after I tried to start several time, about 20 minutes later, it can run and and I drove it well while nothing wrong with it until today.

Today, I tried to start again, it seemed that the ignition worked and engine run to 200-500 rpm, shaked and dropped to zero again. I tried several time. The engine still won't work. I asked AAA to tow it to a local shop, at the first shop( it is a junkyard), one person tried to start( about 1.5 hour later), won't work, he asked me to tow to their another shop. 20 minutes later, we reach another shop. This time the car can start!(About 2 hours away from the time the engine shut down), amazing. After diagnosed the car, the mechanics can't tell me the exact problem and his suggestion was to change a crankshaft position sensor.(He though maybe the sensor was overheated and shut down the engine. But after it cooled down, it will not affect the engine). Since I am in a hurry, I declined and paid him the diagnose fee. And drove all the way down home ( another 150 miles), Now it runs like nothing happen.

Btw. The mechanics has read 4 codes from engine which were: 1106,1189,1404 and0420. I knew that 1404 and 0420 were always there, and even 0420 was there for more than one year ( the engine light was on for about 1 year), The men tell me that 1106 and 1189 had also nothing to do with the engine shut down.

Any idea? Thanks

I have a 2000 old alero and it wont stay running. It will turn over and idle but it idles low and when I put it into gear and give it gas and release the gas it dies.I have changed the fuel filter and I can hear the fuel pump kick on when I turn the key over. Can you tell me whats wrong with my car?

Ok thanks but how would you check that?

Ok I dont have the money to rent one. And I figuerd something out every-time I disconnect the negative battery terminal and let it sit for about 20 mins and reconnect it it starts right up and will drive with no problem but when I shut it off and try to start it again it does it all over. Would that mean that my fuel pump is going out or could it be something else?

Engine Power was lost while driving on the highway. Steering locked up. After complete stop attempting to restart and it would not. I waited about 10 minutes. It started up with a very heavy rumble. Then about 2 minutes of driving and the engine died again and the steering locked up. I waited 20 minutes this time. It started up, no heavy rumble, made it home okay and here I am. The fluids were find. The air filter and sparks were fine (i just changed them along with the wires 6 weeks ago). Could it be electrical or fuel related? Please advise?

Scaned for codes but nothing. I hear the fuel pump kick in.

My Alero starts up with no problems, does not shutter or choke while driving either. After a few minutes of driving it occasionally will try to stall when accelerating from a complete stop(stop signs, traffic, red lights), especially on an incline. I recently had to tighten the catalytic converter to the muffler with some coat hanger wires and a new clamp to hold it in place, and it does not seem loose. I did recently find out I lost a lot of oil after my last oil change. The dipstick indicated the oil barely made it to the letter A in then "Add" portion of Add 1 Quart. The oil change was maybe 2 months ago. I added fresh oil and it seemed to run better, but the problem remains.

Any ideas of a place to start checking/testing? I will be doing a scan at Advance Auto Parts today and bring back any codes I receive.

The car doesn't stall in any gear aside from the first gear and only attempts to stall from a stop/incline. Any information you can provide is appreciated.

This will be updated as I go along.
