It’s done this twice now. The first time it happened it started fine and I drove off but a few minutes later the high idol kicked on as I’m driving 30 mph and poof!! dead on Main Street for 22 hours. A couple days ago on a cold cold morning I started it then a few seconds later the high idol kicks on and BAM! it died, I tried and tried to start it but not even a hesitation like a gas engine without spark plug wires. I disconnected the batteries and gave them a good charge overnight but still no start.
