@Guppysnail, prior to your response, I pulled it out to trouble shoot. Took it apart, cleaned the felt discs in the air stone, played with the pressure, and cut the pigtail hoseline to the airstone. It works fine now, not sure exactly what I did or what was wrong but its going strong.
Unless I accidentally hit a button without knowing it, it should not be in power out mode, but thats something to check if it happens again.
