was actually somewhat kidding - but it most certainly a bad connection, either on the 12vdc r ground side - and could be at the battery or anywhere a connection is made.
It sounds like the connections you mention were all coach builder connections. Had a similar problem crop up last Memorial Day with our ‘02 Georgie Boy we are the 3rd of 4th Owner of in ‘20.
All was good until we were getting ready to lift the jacks and nothing. Control panel was dead. No click, nothing.
Son-in-law started fiddling with wires under the dash while I’m trying to snoop around under the hood and interpret the wiring diagram in the heat of the day.
All of the sudden, the control panel lit up. We got the jacks up, drove home.
Later that week, I got under there and started cleaning up the spaghetti of factory wiring - found where a 1/4 QD connector had a poorly stripped wire crimped inside of the lug making the connection intermittent. I had been snooping around under there the week before trying to figure out why the driver side power mirror that I had fixed a year or 2 earlier had quit.
Replaced the lug - the jacks never worked better (and work like they are supposed to) and the power mirror now works!
In your case, you have a bad connection somewhere. When it’s cold, it may pass plenty of current to operate things, but as the poor connection heats up (due to the current flow), things begin moving due to thermal change, and the connections resistance goes way up or breaks altogether.
Could be in the fuse block, could be a ground bond for your coach batteries (could even be a weak battery).
You really need the coach wiring diagram to help you find the common wiring between the items you say quit working.
Since you have an ‘04 Pace Arrow - touch base with Flyer15015 - I think he has the same coach.
