Sounds like impellar may have trash in it. Take out pump basket and use a short pair of needle nose piers or even tweezers and reach into back of hole at bottom of pump basket to remove trash. This is the easiest way instead of taking pump apart.

Might also be getting air in the line. If you look at the lid of the strainer and can see the water swirling around in the basket, the o-ring is letting air get in. You might have to replace the o-ring or might be able to just lube it to get it seal.
