Intermittent Power Outage

[Seadog]

I have a 2004 2320 Sport cabin and ran into an intermittent problem. While we were fishing the power to the chartplotter, depth sounder, vhf radio and dash power outlet all went dead. The Yahmaha gauges were unaffected. We had been fishing for a couple of hours before the power failed. Later, as we headed back to the marina, the power came back on.
Any ideas on what might cause this problem?

Do you have raymarine stuff?

Check breaker coming out of battery switch. Check to see if it has tripped. I bet if you wiggle the lines out of the breaker, power will go on/off.
