I have been having an intermittant problem with my 2016 G2 250. While cruisiing it will just die at random times. No codes thrown. It just dies as if the kill switch was pulled. I put it in neutral and it usually starts back up. This last Sunday coming back to weigh in for a tournament it did it five times in a mile stretch. After the third time it would not start. I turned off the boat ( Ranger 520) and back on. It started up and I got back to the ramp with it dying a couple more times.
If you have the dashboard keypad instead of a keyswitch, that could be an intermittent problem that your boat dealer may have to solve.
If you have a traditional keyswitch, then there may be service literature or bulletins about that. See your Evinrude dealer concerning the engine stopping issues.
