Engine stalls at speed and idle after hot

I have a 1988 dodge ram 150, 5.2L with TBI. After it's hot the motor intermitantly stalls while driving and at idle. Fuel pressure is good(15psi) and the fuel pressure regulator seems to be operating. Vehicle restarts without a problem, of course it stalls again a few minutes later. Could this be an intermitant problem with the pump? Engine runs smooth otherwise.

Hey man, i own a used 1988 ram 100, it had a stalling problem exatly like yours, and it turned out to be a distributer cap arcing, take it to the garadge and have them hook it up and fix it.;)
