No fire to the distributer
1979 F150. When the truck gets hot, it quits running. It has no spark going from the coil to the distributer. It does have power coming to the coil. While checking it I noticed that when you let go of the key after cranking, the coil spits out a nice spark. But that's the only time. However, once it cools down, it will run fine until it is hot again. I replaced the ignition box. Does anyone know what is wrong? Thanks.

When the coil is hot ,take an Volts/Ohms meter and do a resistance test between the terminals.
See what the OHMS values are.
Ignition coils go bad too.

I would put money on the pickup in the distributor. in my expeience with ignition coils, they either work good or dont work at all. Anyway, my 2 cents worth.

Had the same problem. Ran fine until it warmed up and then nothing at the coil. I had an Accell super coil on it that was brand new so I didn't check it. Replaced carb, Intake, thinking it was a fuel problem, plugs, wire, ignition box twice, voltage regulator and got no change. Gave up and put it in the shop.
Turns out the coil was bad. Bad out of the box. Asked around and found I wasn't the first with problems with Accell products like that. I have the cheap generic coil on it now.
