I have a ceiling fan fixture with lights. The fan runs fine for a few hours or so and then suddenly seems to lose power and slow to a stop. The switch stays on and the circuit breakers are not tripped. I have to toggle the switch repeatedly to get the fan to work again. The fan worked fine for several years so I don't think it's a wiring issue. Any ideas what could be wrong?
In case it's relevant, the fan switch is on a wall panel of three switches. There is one switch for the fan lights, one for the fan itself, and one for a wall outlet in the room. The outlet switch stays on 24/7 and both the outlet and the lights work properly.
