So far on this vehicle within the last month or two. I have replaced the ignition control mod, pcm, both fuel pumps, and the coil. I'm lost on what is wrong with my Bronco, after the engine warms up, it runs fine for about 30-40 min and then just dies. It always starts back up but has to sit for at least 15-20 min. Sometimes longer. If you know what is wrong or even have an idea, PLEASE HELP!

Check and test the inertia switch, fuel pump relay and ignition switch. Power the fuel pump pink and black wire and see if it goes over that time frame.

Disconnect the inertia switch and jumper it and see what happens.
