When you lose prime is the filter pressure dropping to zero?
What condition is the pool in now? Clear, cloudy, filled with algae?

maybe i'm not losing prime.when i turn on the pump it starts out with 15 psi and has good
flow back to the pool.but after awhile when i vac or not the psi goes up to 20 or so. and the
flow back to the pol drops off to a drizzel.if i shut it down for awhile and restart same thing.
so i don't get enough time to vac up the bottom.the pool looks a little cloudy but i can see the bottom.the pool was hard plumbed to the skimmer .so i tried a hose instead still the same problem
check to see if all the fittings were tight and they are .also has a new filter head that didn't
fix the problem either.

When the pressure rises like that it means the filter is getting dirty. Backwashing should bring the pressure down and restore the flow. If the pool is cloudy you want to make sure any algae in the water is dead. How fast a filter gets dirty depends on pool condition, chemical balance, size of the filter and probably some other things I'm not thinking of.
It is normal for the filter to get dirty when the pool is dirty and you're cleaning it up.
