freshwater pump maddening problem
The freshwater pump in our RV (2007 Itasca Navion) stopped holding pressure - it would run up to pressure, stop, then cycle every 15-20 seconds (estimated; never timed on the old pump). Based on advi...

Is there a water filter located under your sink somewhere. In my rig its's under the galley sink. Check that for leaks/cracks/that it's securely tightened. If it wasn't winterized recently, it could have frozen and cracked. They do get missed sometimes.
Is the water pump filter/screen inside the little plastic igloo securely tightened? No idea where your pump is located or how difficult it is to reach, but check it if you can. Also, I've sometimes had the pex water hose connectors loosen at the inlet/outlet fittings at the water pump. Check for tightness. I'll assume you know all of this, because you've replaced it once already.
Have you checked the intake hose valve if your fresh water system came equipped with a syphon tube and valve, to let you put RV AF in the tank when winterizing? Just another useless sinlge point of failure, if you ask me.
Lastly, check the pex fittings on the input/output hosess at the water heater. I had a brand new class A a few years ago, that came from the factory with some of the hoses barely hanging on to their water heater fittings.
Check those items, if you haven't already.
Sorry, best guesses, as it's hard to troubleshoot over the net.
