2003 410 Sundancer - Ignition Breaker Intermittently Trips

[Stromeister]

We have a 2003 410 Sundancer with 3126 Cats and a new issue has surfaced with the ignition breaker in the circuit panel intermittently tripping and killing the port engine. We can be cruising at 20 knots and the port engine will shut down and when we reset the breaker in the circuit panel, it will start back up and run fine for a period, sometimes 5 or 10 minutes, sometimes an hour. Ideas on where to start to find the gremlin?

I would start be replacing the breaker. They can/do wear out. Or swap it with the strbrd engine to save the $30 on a breaker if that's not the issue...

Swapped the breaker with the starboard side and made the 2 hour trip home this afternoon without reoccurrence. Have you guys found a good source for the 10amp breaker? I'd like to keep one on the boat in case the issue arises again.
