I was heading to fill up the RV to be ready to pull out to head to Ohio tomorrow for the fall get together. Making a turn on to 4 lane high way it quit. Checked and had fuel pressure and the carb had gas.

Some one stop by and help me get it off the highway.

After getting pulled off the road and getting ready to start to check it out I tried it and it. It had been sitting for a while as I had to go get tow rope. I tried it and it started. Went home. Replacing the HMI coil. What the chance of it being the ignition module?

Possibly the heat sink compound below it has turned to hard stuff and dried up and shrunk. This would allow it to over temp after a while. Cheap fix. NOT dielectric grease, heat sink compound.

Sounds like the same symptoms I once had on an 84 chevy van. Long story short... Once the module was replaced with fresh heat sink compound the problem was solved.
