Electric outlets work when generator is on but stop as soon as generator turned off. The battery is switched on. Any suggestions?

Agreeing with QCMan, we need a bit more info.

But generally as he said your electric outlets and air conditioner are 120 v AC and will only work when plugged in to shore power or with a generator. The rest of the coach (lights, water pump, furnace etc) is 12v DC Battery powered.

Plugging in to shore power will start to recharge your batteries.

I’ll guess. You don’t have an inverter, so the AC receptacles should not work when unplugged from shore power or genny turned off.

Some good reading to introduce you to the 2 different electrical systems in your camper.

The outlets are not 12 volt powered. One would need to add an inverter to have power without the generator or shore power.

A bit over simplified.....

Electricity comes in two flavors:

 - AC: Alternating Current: This is the power you have in your house and the outlets that look like the ones in your house. It's generally runs around 120 volts but 60 times per second, it reverses direction. Usually, you get AC from plugging the RV into a shore power pedestal or your generator puts out AC.

 - DC: Direct Current: This is what your batteries put out when you call on them. It generally runs around 12 volts and stays in the same direction. Your car starter for example runs on DC. 

There are devices in your RV that run on AC and those that run on DC.

 - All RVs have a battery charger (aka: Converter). This takes AC and converts it into DC for direct use and to recharge the battery.

 - A small percentage of  RVs have an inverter. This takes DC and coverts it to AC, so that you can use AC while disconnected from an AC source. Of course, it uses up the battery power, so it's limited in what it can run and for how long. 

My bet is you don't have an inverter, so when you shut down the generator and are not plugged in, there is no source for AC power and thus your outlets don't work.

You do not give enough details to give a proper answer to you but generally the outlets only work when there is input to the trailer from the generator or shore power. You do not state if you have a battery bank and inverter so the above is the best answer to your question with the info given.
