Deep well, pressure switch stays on (closed)

The only way I have water pressure is to leave the power on!!

I have replaced the 5 gallon pressure tank (28psi when void of water)/fittings/pressure gauge and tried 3 new 30/50 pressure switches and the problem remains the same.

With the power off, the pressure drops to 0 (not 30). When I turn the power on, the pressure builds to 28-30psi (not 50psi the cut-off) and the pump shuts off and drops down to 0-5psi then cycles back on again, building back up to 28-30 psi. This is very aggrevating when taking a shower.

What is supposed to be the cut-in pressure, is when my pump cuts off. It never see's any pressure above 30psi. If I tighten down the cut-on pressure nut, when the pressure reaches 30psi, it just stays there and the pump runs constantly unless I trip the breaker!

I know leaving the power on is not good for the pump.
