Problems keeping prime in freshwater system

My pressurized freshwater system went out recently and I isolated the issue to the pump. Having replaced the pump I had problems getting prime until I fixed a loose seal on the strainer. After taking care of that, all was well - no prime problems, good pressure, acceptable flow. I left the boat for a weak (all dc power off) and when I returned no prime. After activating the power the prime comes back but then fades out completely after only 20 sec with a faucet on.
The system is a bit complicated. As far as I can tell tank water runs from the forward tank (under v berth) to a canister filter under the galley sink. It then routes back through the pressure pump, which winds up feeding two heads with showers, and the galley sink. I'm sure the new pump is okay. Thinking it must be the canister filter? Or maybe an unknown leak somewhere?

Sounds like a leak somewhere in the system. Is water finding its way into the bilge?

No water in bilge as far as I can tell. (But its not the cleanest and its hard to tell). Have checked connections at outputs and all seem tight.
