    A tuneup cant hurt. If that dosen't fix the problem rebuild the distributor. The bushings wear out and cause them to stall at stops and idle.

    Change the pick-up coil. Mine was doing the same thing......I also had to change the main shaft int he distro as it was no longer firing the pick-up through the reluctor wheel. Not very common though.

    Have you Checked for trouble codes?
    If there are none. Then try replacing the distributor module first.
    Your problems are pretty common indicator of a bad module.
    A bad pick up coil will usually throw a code 42.

    Mine was doing this "cutting out" thing a little while back, and i did the changing of a bunch of parts,, thought i had fixed it until it wouldn't start one morning,,,ended up being a bad injector.

    I never got any codes with mine.
    The neighbor did get a 42 but his reluctor wheel was missing one of the tongs..

    I think blottozone might test the module for free (but don't quote me on that).

    never received any codes from mine either, would be driving down the road, and it was almost like you would turn the key off real quick, and then turn it back on, the engine would literally just shut off for about 2-3 seconds, and then get going again.

    no codes, no lights.

    $150 for a new fuel injector from Napa,,,because Autozones was a serious P.O.S. and it's been running great ever since.
