That's a new one for me? I've never heard of a water pump continuing to run after the faucet was shut off, except when they start sucking air due to a failing pump or a valve left open.
Considering the pump functions properly when hooked up to shore power or a generator, you can run a simple test on the strength of your battery.
Disconnect from shore power, do not run a generator, and now simply turn on an overhead light and see how bright it is. Now turn on a second light. If the first light dims noticeably, then the battery is weak. It's not holding a full charge. Of course, disconnect from solar too when you do this.
