After reading your post you said that even when on shore power your “disconnect event” makes the voltmeter reading drop to 0 volts if I understood correctly? Do the 12vdc loads (lights/fans) in the coach keep working or not during the “event”, when on shore?

My first thoughts on your situation is that it is not a DC breaker tripping since your 12vdc comes back without resets (unless the breaker is not sitting in a panel correctly etc)........might be a relay that is dropping out for some reason......but I thought a bad/loose or dirty electrical connection somewhere that makes (works) sometimes and breaks (opens) other times is more likely the problem.....maybe temperature or motion sensitive?

The gen probably stopped when the “event” killed he 12vdc supply feeding the gen control unit. If 12vdc is lost from the coach DC fuse panel during these outage events I would start by checking all DC connections from output of converter to DC fuse panel. Also use a voltmeter to test where the 12vdc is good and where it fails during the failure event.
