I went ahead and cleaned out the airline tubing with ro/di water which, as always, seems to help. But my final consensus is that some PE Mysis I was feeding caused the skimmer to shut down for a few hours. Sometimes it can be hard to point to one specific thing that causes a slight problem. Everything seems to be back up and running properly now.
Thanks for your help.

It could be the pump is possibly beginning to fail, since it isn't pushing in enough water and air. Or perhaps you have a vapor lock issue, such as placing a cap on the riser tube like I do. If it seals tight with salt creep, the water level drops in my skimmer as well.
