With only those details I would guess a transfer switch or relay not operating correctly or in the wrong position.
Good luck, keep us informed.

No 12 volts on this fridge. Just 120.
50amp is still single phase isn't it?
Our boat has 50A/120V and 50A/240V and our marina was able to supply us with both. On my power panel there's a switch position to accommodate if we're visiting a marina that only has 120V and we're using two 30A inlets. That gives us 50A/240 and 50A/120 through the panel.I eill check... But that would be weird. I thought all US marina 50amp was 120v.
Grab a multimeter, super useful to have on the boat and would help a lot in this sort of troubleshooting.
Check the breaker on your DC panel.Fridge ran off shore power fine.
Eight hour trip, now it only runs off generator.
What is the answer to this riddle?
