If I fill pump well full of water, for several minutes, it bubbles and fills up, close lid cut on pump, it starts prime sequence, sucks all water out of line, then just runs dry. What could cause this, something stuck in round from pool to pump? I have tried it with valve on main drain, and on skimmer.

Water flows fine through sand filter and pool jets, until it just runs dry. I refill main line, one time for like 10 minutes, it would bubble every now and then, but no water returns to pool, unless it's through bottom drain maybe?

Could I have a clog? Or a broke line? I live in Florida, and it was 75 degrees today. It was working fine yesterday. Wife was kind, and cleaned pool yesterday, so maybe something happened with that?

I leave to go out of town for a while tomorrow, so really don't want to leave it shut off. I know pump run dry, it will burn out. Any help is greatly appreciated.
