our 15x30 oval has 3 return jets fed by a single pump (it's slightly oversize in h.p. I think and I'll post model later, but it's not unlike the below picture, but in tan)

We're all algae'd up. We need to keep up on cleaning, but we've shocked it a few times and I'm thinking the "basics" are failing somewhere.
The filter is an S244T2. I checked the sand level and it was below half. Some does spill out to the front where the backwash feeds. I've added sand since then; I suspected it was low enough that the backwash wasn't clearing out the muck or the filter wasn't pulling through a uniform level of sand thickness with it being below half. I was advised to run it a little lower than mfgr. recommended.
Back to the thread title. Pumping is stopping. I keep the o-rings lubed yearly and all are fine. No air bubbles are coming out of the return jets (unless I have switched from backwash to regular or had the valve off to fill sand or something like that.) And it's not losing prime that I can tell; I don't have to fill the filter basket before starting it up.
In fact, when it's not pumping, I can switch the timer off, then switch it back on and air bubbles come out, then normal pumping resumes.
Possible the pump is going out? Or do I need to idiot check myself and for leaks?
