My bet you are overloading the generator and the only outlets still working are powered by an inverter. What size generator? How many AC's, water heaters, refrigerator, and don't forget battery charging. If you only have a 30 amp service, probably only have a 4K genny or even less. This gets you one AC, Fridge, and some battery charging. This is an entry level or starter motor home designed to a price point to give you an appetite for a next step.
