This can be caused by clogged filters or clogged lines which you have already checked.
Other causes can be air leaks on the suction side of the pump . This causes pressure to Build when you cut the pump on then fall to a lower level.
Places to check are hoses and connections on the intake side of the pump and any pressure relief valves on filters
or elsewhere.
You may have noticed that the pump has been losing its prime.
This leak can be any place That could suck air into the system

This kind of leak can be hard to spot. Using a small flashlight and a magnifying glass can be helpful when inspecting for hairline cracks.
when the system is on you may hear it sucking air at the source of the leak unfortunately this is not always the case
You made need professional help to find a leak of this type
