Engine shuts off? Long warm ups
1978 F250 4x4 400 engine stock everything
I live in Los Angeles where the avg. temperature is 60-80 degrees. I understand carbed engines need to be warmed up but mine takes 10-15 minutes is that normal? I know its ready when the engine smooths out other than that if i attempt to drive it too soon it dies. Sounds like as if it floodded and sputters and dies. But if I wait it out till its completely warmed up it runs perfect.
Also the question I would really want to get help:
After 50 miles of driving my truck suddenly dies, either on the freeway or stop and go as if it sounded like it ran out of gas. I put the truck back to park, started it by having the gas to the floor, but when trying to start back up it sounds like it needs to warm up but only for 20 secs than when I shift it to drive about 2 feet later it dies. So i left the truck there, and few hours later went back to start it, ran like a champ. I am guessing its the ignition module, seems like giving it time to cool down works. Any help appreciated.

That sounds like the symptoms of the ignition module. The type of module, in general, is determined by the color of the grommet where the wiring plugs come out of the module. Autozone and other parts stores will check the modules free. Motorcraft modules are still readily available - stick with those. Mount them with 1/4" space behind them. I believe Eric (Torque1st) indicated he used 5/16" nuts as spacers. I still haven't gotten around to using the spacers on mine. Find a parts store that carries Motorcraft. Don't know if you have O'Reilly Auto Parts in your area, that's where I get Motorcraft parts here in East Texas.
This problem could also be the pickup module in the distributor.
Hope this helps.

Sounds like I had the same problem as you have. Drove me nuts, truck sat there idling fine and I shut the door and it quit. traced it to the starter solinod on fender. It developed an internal short which caused power loss to the ignition. It always rolled the engine over just fine. first a bump in the road then simpley going from park to drive the engine would quit. starter solinod $7 bucks good luck
