I have a well experiencing some pressure issues under load. Once triggered by the pressure switch, the pump seems to run about 20 seconds or so and then shuts off of its own accord. Checked pressure switch and it is kicking in and out properly at 30/50 PSI. What happens is: Switch triggers pump. Pump runs building pressure, but turns off in 20~30 secs even if it has not hit 50 PSI. Pump sits then turns on again (30 seconds to 2 minutes later). Then off again, then on, etc., until the pressure switch kicks at 50 PSI. Under high water demand, house pressure settles to zero eventually, since pump spends too much time off. I checked electrical and even though the pressure switch contacts are still closed (under 50 PSI), there seems to be no actual current across the switch contacts when the pump has short-cycled itself off -- suggesting that the electrical circuit has been interrupted somewhere other than at the P switch.
Could this be the pump kicking itself off for some self-protection reason? Anything else in the pump-side electrical circuit that can open up intermittently? How can I diagnose? Thanks for your thoughts!

Well 250 ft drill, unknown water level. Gould is a 5SB05422. Two wire system. Preassure tank well-x-trol 32 Gal, verified good membrane and correct preassure charge (however, it was a few pounds low when I bought the house.)
