You may have a converter issue. Have you checked to see that the battery disconnect is turned on? , meaning that battery power is able to get to the power distribution panel.

Hi GSport. Welcome to the tech forum.

As Brian mentioned, this is a classic sign of a converter that is failing or has failed. You don't mention what type of rig you have. But if it's a fifth wheel, the converter is typically located behind the "wall" in the basement storage area. The problem could also be related to a bad battery.

Here is a trouble-shooting guide for checking it out.
