It runs 5-30 seconds and shuts off. Replaced fuel pump, regulator, Idle control, Throttle position censor, and computer still does same thing, ran several miles with new computer

If there is a problem with wiring circuit somewhere, replacing the part won't fix it. Can you tell if your losing spark or fuel when it stalls? Any applicable mil codes?
