Question about Plumbing
I checked and set the pressure in my captive air tank by the proper procedure to 40 pounds( shut off pump, drain system of all pressure , check tank pressure, set to 2 pounds below cut-in pressure of pump). After a short ime noticed that my water pressure would drop to almost nothing before the pump kicked on; a classic symptom of the pressure in the captive air tank being too high. When I checked the pressure in the tank again, by the same method (pressure drained from system) it read 55 pounds. I thought I screwed up so I readjusted the pressure to 40 pounds. The next day the same thing occurred. I checked the pressure in the tank (again, after draining the system) and the pressure was back above 50 pounds. Yesterday I set the pressure at 10 pounds. The water pressure in the house seems good now. I checked the pressure in the tank (again after draining the system pressure) and it's now at 13 pounds. Can someone please explain how the air bag is gaining pressure???

If heating up, the motor thermal switch is opening to shut down the motor; this is by design. During the brief run time does it pump at all? It sounds as if there may be mechanical issues on the pump itself and the motor (from the extra draw) is heating up and shutting down. I'd look in to the pump to see if anything had failed within it.
I hope this may have helped,

My first thought was that of a water logged tank which causes short cycling, from your notes the tank is good (the tank may be partially water logged though) If the tank is ok and your getting short cycling (and the switch is good) I would guess your check valve down the well has failed. As the pump creates pressure then shuts off the water may be going right back down the well causing the pump to cycle again. This could also account for the poor water pressure as the check valve may be stuck slightly open allowing the system to loose pressure but only allowing a small amount of flow by when running. There could be a leak within the pumps drop-pipe and your loosing pressure through this leak. I expect you'll have to have the pump pulled.
I hope this may have helped,
