DE-451 working fine on AC and come back days later and is off Turn off and on again to get it back on any ideas

DE-451 on a boat 1999 era with both AC and DC. When on shore power AC it sporadically will stop working. I have to turn the cold switch inside the fridge off and on to get it back on and then days later it will be off again. Any ideas on the problem? Does turning off then on reset circuit breaker?

When it quits on AC every few days and a power cycle brings it back, it's usually the AC power supply dropping out (it overheats or has a failing part) or a loose connection. It's not a breaker. Check the AC connections, and make sure the fridge's vents have good airflow. On the DE451, the power supply is the 160113911.
