I was at a stop light on electric with a range left of 20 plus miles. The signal changed step on the gas and nothing. Car behind me started hooking, instinct panic, I turned on the flasher pushed the power button to turn everything off, then pushed it again and everything was fine, except maybe my underwear LOL. Has not happened again. I had put a new 12V battery in a few months ago. Also did not notice anything unusual on the gauges. My main thought was to get out of there , not the best area to get stuck in.
