    there is no ballast resister. it is built into a coil on a 88 or should be if you bought the correct replacement coil.

    what about the hall effects sensor in the distributor? was is replaced?

    since it shuts off like you just turned the key off i doubt it but it sounded like you were throwing parts at it anyways. it almost sounds like the pcm might be going bad but i don't know if there is any way to troubleshoot that and they are not cheap.

    I second the pcm option, or possibly fuel pump.

    On a newer ram I had similar issues, only it would stop at random, replaced the fuel pump for good measure and then replaced pcm when that didnt fix it.

    Hope you get it going those are some great trucks! and can last forever!

    i think the fuel pump is less likely to just kill the engine like you just shut off the key. the TBI only requires 15psi to run so it is more likely to act it is running out of fuel a bit before it just shut off if the pump was the issue.

    I did replace the PCM back earlier in the summer, no luck, same symptoms
    It cost me about $215
    No hard to change
    It is just behind the battery
    I thought about the fuel pump too
    But as crazywolfe mentioned I think it would start acting like it is running out of gas instead of immediate shutoff
    Thoughts???

    have you checked for spark when it shuts off but won't restart?
