can't keep prime in pump

[topless]

Something is blocking water to the pump or there is an air leak on the suction side of the pump. Those are the only 2 things that will do what you are describing. Since yours is an above ground pool and the water level is above the pump, my guess is you have an obstruction in the suction hose.
