With the engine cool, make sure the radiator is full and the overflow bottle is about half full. ---

Did hellokit’s suggestion help? If not, an intermittently sticking thermostat could be culpret- when it’s stuck closed, engine heats up, and you get hot air; when open too long you get cooler running engine and not-so-hot air from heater, but maybe first get cooling system pressure checked to see where antifreeze is leaking.
