1989 chevy g20 STALLING

I have a 1989 g20 van that keeps stalling.It will run for awhile then stalls and wont start,after a few minutes it will start again.I've tested the fuel pressure by cranking the engine for 15 seconds and got over a pint of fuel.I had the ignition module tested and it passed.I disconnected the knock sensor to see if maybe that was it but it did the same thing.the fuel pump is a little over a year old.recently replaced the plugs and wires.rotor,cap and the coil.also put injector cleaner in the fuel.Also I pulled the tank out and tested the fuel pump and it passed.Any Ideas would be GREAT
Thanks,Tim

Normally on chevy ignition modules when they go bad, they will quit when they get hot & after cooling down will work again, so when you have them tested they have cooled down. I would try changing it & see if it wont fix it.

At what point does it stall? Does it run for a few moments before stalling? If so, it could be a faulty IAC (Idle Air Control).

1994 chevy pick up c1500 stalled out while I was driving


This stalling is fuel related issue.When the fuel flow becomes low, the engine ask for fuel.But fuel pump does not send required fuel and engine stalls.In some cases, it stall then dies after stalling for few minutes.In some cases, if stalls for few seconds or minutes, then again get required fuel , as you accelerate more and engine starts/runs normally.But once this problem is started and it repeats again n again.This is indication f low fuel pressure.Get the fuel pressure checked and replace fuel pump and fuel filter.-----------
