Hey Chris. My B2 (and I think all of them) came with a vibration pump. I'll add photos below of that and a rotary pump. In my experience with the vibe pumps, I found that they did in fact wear out, especially if the pump was run dry. My reservoir switch (the one that turns off power if the reservoir runs dry) came wired backwards from the factory, which I didn't know until I had killed a couple of pumps and we finally found it. Also, the overpressure valve (OPV) lost seals a time or two and replacing the OPV or the seals fixed that problem.
I did have similar symptoms to you on several occasions, and though I don't remember the specifics, I do remember that it was always pump or OPV that fixed it. I switched to a rotary pump (with it's own pressure setting) about 5 years ago, and I think I have my old OPVs and pumps and would be happy to send them to you if you'd like to try them. I'd also start by checking to see that when you lift the reservoir, power is cut to the machine. If not, you need to switch the wires below the reservoir. Along similar lines, I never used the water softener on the pickup line in the reservoir, and once discovered that my intake line was floating, so it was sucking air and I killed a pump that way too. It needs some sort of weight if you don't use the softener cartridge.
