Stalling after 15-20 minutes......
I have replaced the fuel pump, the filter, the relay & the ICM. I let it run for about 15-20 minutes & it will not start bck up til it cools down. Can someone help? It is a 95 4.3 2nd gen motor....ICM is on coil.

When the ignition is initially turned to the RUN position, (engine off) the fuel pump will be activated for ~2 seconds and then shut off. This time frame is referred to as "pump prime" and fuel pressure must be tested during this time. Fuel pressure must be 55psi to 61psi and must remain above 50psi for at least 10 minutes.
