Air Conditioners shut off

2019 Cyclone 4270, we are boon docking and running the generator. I turned on the bedroom AC and the garage AC and they ran for a minute then shut off. I checked and find no breakers tripped and I think we have power everywhere, however neither the bedroom or garage AC will run. Thankfully the living room AC is running...…..any thoughts on what I can look at.

PCS is detecting you have 5500 watts and is probably shedding power. Try switching water heater to propane and limit other 120V devices.

Thanks Dane.....I did not think to check the breakers on the generator. One had tripped. Reset and all is good. Thank you for taking the time to respond.
