Hello! 2003 2112 info?

[Camper Bob Ottawa]

Good evening.

I'm Bob, from Ottawa, ON, Canada.

I'm looking for any info on why (other than it's 15+ yrs old) our 2003 Starcraft 2112 pop-up trailer power keeps dropping off/shutting down after 10 mins. And yep, I checked the fuses with another fella, and none were blown.

It goes like this:
Plug into hydro.
10 mins later, zero power to the trailer.
NO breaker switches were thrown.
The only thing we were running was the standard tiny fridge and a couple of on-board lights; nothing heavy-duty at all.

We have had this trailer for 7 years, and nothing like this has ever happened before.

Is it the breaker switches themselves? Has anyone ever replaced the breaker switches? Is it hard to do?

Any info at all would be greatly appreciated!

Cheers,
Bob, Steph and the three fuzzy buddies.
