I live in a double wide-I keep losing power on one side of the house. It's not even the entire side, maybe half way. Sometimes it will come back on by itself, other times it won't.. When it doesn't come on, I have to shut off all the circuts. Sometimes that doesn't week and I have to just hit the circuit breaker on one of the outlets.. any ideas?

Likely at the last good outlet or the first bad, Sticking wires in the holes instead of tightening around screws is famous for doing this.
If you are going to go through all the recepticles, you may want to change to Decora. Labor would be about the same, just need the recepticles.
Is it along a wall on 1/2 of the dbl wide or where the 2 connect, could be at the splice box between the 2, may be in attic or underneath.

You probably need to have your electrical panel and breakers checked. If you hit trhe breakers or turn them off and on to make them work you might have a bad breaker or burnt connection in panel.
