I'd also check the secondary resistance of the coils when the car dies. Suspect heat failure.

reggio, just to clear something up for us, explain how your car shuts down and under what conditions. Remember that we are nowhere near your car and therefore need as much detail as is possible in order to provide you with any kind of advice, especially if you are wanting good/useful advice.

Secondly, let us know what the maintenance level is on your car.

Any recent work done on it?

Tune-up lately?

Last time you had new plugs, wires, other maintenance done?

The more information you provide to us, the more likely it is that we will be able to help you find your problem.

Thanks.

The car just shuts down.I drive and suddendly the car shuts down.Sometime I see the oil level idle mooving(not stable from left to right) and also the battery.But when the car shuts down the battery level is normal.I changed the alternator 3 months ago.When my car shuts down it can take up to 5-10 minutes to restart it.And then the problem can persist or not.Thanks a lot

Okay, when you try to start it, What does it do? Nothing? Crank but not fire? Fire then stall?

After it shuts down while you are driving it, does ittake a while to restart it agoin? If you dirve it and turn it off regularly, does it start up right away usually?

If let`* say I have to go to the store and park the car , after it restarts with no problem.It`* when it stops during driving, that the car doesn`t start right away.It can takes up to 5-10 minutes more or less to restart.The challenge that I have is that when the car stops I don`t have a computer with me.And when it restart and I bring it to the garage there is no service engine light on so i can detect the code.

Thanks

OK, well first off, if the CEL/SES has been on at all during one of these "episodes" then the computer will store a code...even if the light is off when it gets to the shop. That code or codes can be read and used to help diagnose the problem.

If it were me at this point, I believe I would do a fuel pressure test.

The ICM could also be heating up.

Look in TECHINFO above for the method to test your coils.
