Here's more detail. The refrigerator turns off (no power to the fridge) after some period of time when on auto (LP/AC) and plugged in to shore power.
I would think it if it lost power (unplugged from shore power, blown fuse) for whatever reason, it would switch to LP but the refrigerator simply turns off.
On LP only, it works fine.
We did switch shore power to another 20 amp outlet, thinking the first outlet might have had too much draw. Refrigerator stayed on for almost 24 hours, then lost power again.
And thanks to those who responded. We are just in love with our new rig and want to be sure all systems are working correctly.

Yes, 20 amp from our house. I realize this is a 30 amp rig, but we're running just the refrigerator and an occasional indoor light. We've never had issues while hooked up to our house 20 amp while we pack up for a trip, etc. Plus it's only the refrigerator that loses power, not the lighted microwave, thermostat, etc. which are plugged in but not being used.
The 5 amp fuse behind the refrigerator was checked and appears to be good. When the check light comes on, it can be reset immediately. I'm just wondering why the check light comes on in the first place. And, if on auto, I would think the refrigerator would switch to LP when it loses electric.
