Ford Repair: Stalling Problem in Ford Pickup, fuel pump relay, ford pickup

Question
I failed to mention in my previous email that we do have fire, no fuel pressure.  With fire, do you still think it would be an ignition module problem?  Just as soon as it dies and we check for fire and fuel, we've got fire, no fuel pressure.  Thanks again!

Hello, I've got a 1991 Ford Pickup, with a 460.  The truck will start and run fine for about 30 minutes, then stalls.  After letting it set for 15-20 minutes, it will start back up and run fine.  Then the whole process repeats.  I have replaced the fuel pump, the fuel pump relay and checked all grounds, to no avail.  The problem is still there.  Any clues?

Hello and thanks for the question...I'll try to help.
I would suggest that you check the computer system for fault codes and I think you might find that the ignition module is failing.
Hope this helps,
Erik

Yup....knowing that in the first place would of helped.
Since you are losing fuel.....the only other thing in the system is the computer to apply voltage to the fuel pump. I would strongly suggest that you check the computer system for fault codes.
