I had the weirdest thing happen Sunday. My system goes on at 7:00 am everyday and runs for about 8 hours. (Overkill, I know. 
) Soooo, Sunday morning I'm outside cleaning up bit and the pump kicks on as it should. After abut 30 minutes I think I'm hearing sucking sounds. I see the Weir door on the skimmer is vertical as if there's no suction flow and verify there is no water flow through the return eyeball back into the pool. I shift the Three way Jandy valves and can hear there is indeed air in the suction lines. Quick as a 67 year old can move, I get to the pump and see the pump strainer basket is bone dry. I shut-her-down, and take a breath. open the vent on the cartridge filter and listen to it re-fil. Then open the strainer basket a bit and fill it with water as well. I restart the pump and watch. I see some air bubbles pass through the strainer basket from the suction lines, but within in minutes, everything is back to normal. The pump shut down at 2:00pm, like normal, without any further difficulty...What could have happened overnight that would cause that to happen? Where should I look?

might need to trim a little off the edge that’s sticking.
was up against the front of the weir door and the skimmer basket had floated up against the back of the door. The strainer basket was actually holding the weir door up...(Closed?)
