More fun with a well pump, pressure gets to 20 then drops to 0

I'm having a new problem with my well water: when I'm running water the pressure will get to about 20psi, hold for about 5 seconds, then drop to 0! After about 2 seconds at 0 I can hear it kick on, and then the pressure jumps up to 20 and climbs back up to 50.


I replaced my pressure switch and well pump in early August of this year (close to 4 months ago). I replaced the pressure switch myself with a Square-D 30-50psi with an Auto/Start/Off lever. The model is FSG2J21M4CP:

That didn't fix the problem, so I hired a plumber to replace the well pump. He said that it looked like lightning had ran in on it.


It also has a Wel Flo Pre-Pressurized Water System Tank, model # 24221808, that appears to be OK.


What do you all think... faulty pressure switch?
