1987 efi 302 shuts down at operating temp
I've replaced fuel pumps in the tank and on the rail. New Ignition wires, plugs, distributor cap, but problem persists. Thinking it could be the EGR. Any comments?
I'd like to trash the entire EGR system. Has anyone out there done this? Would appreciate details.

When it shuts down, is it because you're losing fuel or fire? Your problem sounds like it's ignition related, as many electronic components will fail when they warm up and their internal circuitry expands and breaks contact. When they cool down, the circuitry will contract back to its original position, again making contact and again allowing your truck to run again until warmed up. However, this could just as easily be an electronic component which controls fuel delivery, such as a fuel pump relay. If you're losing ignition, I would suspect the Electronic Ignition Control Module, or the stator / pick-up coil [inside the distributor, beneath the rotor]. Just a few thoughts.....
