A/C and some power outlets went out (no breakers tripped)
I have a 2007 Montana Mountaineer 342pht that's running on 50A power at an RV park right now. It's been really hot where we're at, so we've been running the main living room AC pretty much non-stop. Yesterday, the main AC went out so I just flipped the breakers on/off and it started working again. However, today it suddenly went out again, along with most of the power outlets, but this time no breakers were tripped (flipping them on/off didn't work), and there are no blown fuses. It's strange because the fridge and microwave have power, and the power outlets in the kitchen and bathroom work, but all of the other ones are out.
Does anyone know what might be going on here, and what I need to do to get power back on for the A/C and power outlets?
