Have a 04 grand prix, can start car and drive maybe 15 miles then car will just quit. Usually fires back up in 20 seconds but will quit again in few more miles. New batter, fuel pump, plugs wires and crankshaft position sensor! Any ideals would be appreciate.

    No CE light? Codes?

    How does it shut off? Quickly and the tach drops immediately to zero?
    Or does it strangle and slow down with the tach still reading?

    Fuel pump heating up after running for a period of time.

    ICM under the 3 coils heating up and failing then working again.
    Have you loosened and checked the connections at the front of the ICM?


    These are the compatible ICMs on other cars for the NON-supercharged model
    and the supercharged engine.
    Get one from a pick and pull just to replace IF you suspect the ICM.
