Shutting down the engine

Interesting event on my drive to and from the Overland Expo. I turn the key to off position and the engine continues to operate. I have my foot on the brake. When I release the brake the engine
shuts down, but not until I release the brake pedal. Happened several times, usually when I have been driving for a long time...two to three hours.
Never did this before. Also the number 12 breaker pops occasionally...no connection to the time of engine quirk. Usually in connection with the turn signal being used.
Getting odd this pinz is.
Any suggestions?

I had a problem with my ignition switch a number if years ago. I would turn it off and the truck kept running. It also drained the batteries once. I sprayed electric parts cleaner through the switch and it solved the problem.

Is it the fuel solenoids in the carbs? They should turn off the fuel when the ignition key is off.

I was thinking the same thing. My '71 Nova used to do that some times.

If it shuts off when you release the brake petal, I'd suspect something vacuum related.

There is the possibility that it could be caused by engine overheating. Excessive heat can also pop a breaker. If taking your foot off the brake kills it when it is in gear, I would say this may be a possibility; if it's in neutral when you release the brake, I would lean more towards something else.
I had an old van that I drove home 12 miles after a wreck that knocked a hole in my radiator. My engine was so overheated by the time I got home that I could only get it to die by putting a load on it, by putting it in gear. I later found out that this is called dieseling.

Thanks for that tip...
Heating could be the issue as we were driving through the desert south of Moab on the way to Flagstaff for the Overland Expo. Not had the issue
since then and no 12 breaker popping.
Getting used to all the little quirks my pinz has even after having it for 7 years. Did not have this issue in SoCal in the desert when it was 113 F.
Sort of has a personality of its own...maybe it is transference
