Pump starts off with strong suction and pressure then slows

I have a Hayward pump and filter. When it first goes on the suction is strong. After about 30 min the suction starts to decrease. The pressure does not go below 15-18 psi which is usual. I a have changed the lid and lid gasket, I have opened up the pump and greased all the o-rings and still same thing happens.
