What colour are the wires that appear to be cut? Almost no one connects the kill switch, it’s possible that they are the ones not connected…otherwise, hunt for dirty connector pins/sockets, wiggle one wire at a time and see if it cuts out…that’s your best clue without real test equipment. Check all ground connections, coil to engine case and chassis…sometimes a dirty ground is just perverse! You can find wire colors in the Honda manuals, maybe on line, haven’t looked though. Sometimes a stator coil connection vibrates ‘loose”, still there but intermittent. Some disassembly required!
