My 2021 M65 is having sporadic electrical issues, 3 times in the last month the GPS and gauges all lose power for a brief second and then come back on. It does not effect the tachometer or the main radio but does turn off the helm radio control. The engine operates without interruption. I have checked all the wiring connections and the problem occurs with either battery. The closest dealer is a 3 hour boat ride and I don't feel comfortable going that far in case this is a major problem. Any suggestions would be appreciated.
