    A damaged or uninstalled crank sensor can cause this.

    Also, if the timing gear is damaged (missing a tooth), it will do the same thing.

    Age, but it was only a suggestion. There could be another issue. Is everything hooked up properly?

    Is it possible that you have the distributor installed 180* out?

    If the distributor was 180 out would it even start up and run for a few seconds

    Kinda sounds like if you turn your truck on without the MAF sensor connected. it would start but die a couple of seconds later. the vacuum hose also affects the truck in idle.
