The usual suspects are an air leak on the suction side, often at the pump lid o-ring and low water level letting the skimmer pull air.

Can I fix a pool pump that will not hold prime myself?
You can safely run the first checks: top off the water to mid-skimmer and retest, and clean and reseat the pump lid with a lightly greased o-ring. Anything involving wiring, gas, or a submerged fixture should go to a licensed La Mesa pro.
Does La Mesa's hard water make this worse?
It can. La Mesa water runs 16-20 gpg, rated very hard, and scale from hard water is a real factor in problems like this. A pro will check for buildup as part of the diagnosis.
