I have an 86 F150 that when I run it, it will run fine but after a while of running it will get hot but not get on the temp gauge and then it will stall out and it will crank but wont fire. After it sits for a good half hour it will fire again. Someone told me its the ignition module because they're not located on the fender like the newer models are. Someone said about relocating it but i wanted to see if anyone else had the same problem or knew what to do.
