Usually related to the connection between the battery and the bike. I take the battery out, clean all the electrical connections (both battery and bike) and then reinstall the battery. Sometimes I have to reinstall the battery a couple of times before the connectors seats correctly. Mine also has a connector to the display that comes lose (usually after a crash) every now and then so I would check all the electrical cables as well. Good luck.
