Hey guys,
I have a ‘76 f250 with a 460 engine. I’ve had a problem that is happening more frequently where the engine will die while driving, but cranks back up and starts although sometimes it takes a little longer to start than others.
From what I’ve read it could be the distributor or the ICM. Twice when this has happened though the engine will disengage and is followed by a backfire. Does this still sound like an issue with the distributor/ICM?
Any help is very much appreciated 🙏
Thanks everyone

Classic dura spark module switching transistor failure symptoms.

When they over heat they stop working until cool down. As this continues the recover time increases until total failure.

When I was playing mechanic, we encountered what appeared to be dura spark module failure. It turns out that the flat blade connectors would go into a high resistance failure. When you change the module, you would wipe all the connection surface and all would look well for awhile. Normally the real problem could be corrected buy getting out you needle nose pliers and giving all the flat blades a little twist.
Back in the 70s Champion Spark Plug published a monthly "Tips & Tricks". That's where I learned about the flat blade connectors.
