Auto reset circuit breaker?
 

I have an 89 36' Fever. Several times now after dark when all the nav and dash lights are turned on, all lighting on the boat goes out. The engines continue to run. Then after several minutes everything comes back on and appears normal. I there a master auto reset circuit breaker somewhere? I looked up under the dash but didn't see anything that looked like one. Or any other ideas on what the problem might be? Thanks for any help!

No auto reset breakers. That would defeat the purpose of having one.

Sounds like you have a loose wire some where.

I'd say look for a loose ground.
