Bubble magus skimmer trouble- help!!

[jtf74]

The motor is running but not getting the bubbles. I unplug and plug in and it skims again and works for a day maybe. Nothing is clogged in the airline and the motor didn't look gunked up at all when I first noticed a couple weeks ago. Any ideas on what the trouble may be? It's been running for almost 2 years.

About two weeks ago stopped skimming. Motor still runs and pumps but no fine bubbles. Motor didn't seem gunked or air line blocked. Been running for 2 years. If I unplug and plug back in it works for a day or so then stops producing fine bubbles. Any thoughts?
