Back aways you said you had 'charged the pressure tank to 48psi" If you are referring to the precharge, it is way too high, correct would be about 26psi.
That shouldn't cause the problem though.
It sure sounds to me like one of two:
1. Worn impellers.
2. System has check vavle(s) that isolate the tank when the pump(s) are off and from each other (would take 3). The bad well has a leak somewhere between the pump and the tank checkvalve. That would be my guess. If feasible, try removing or disabling the tank check valve, run the bad well pump as high as you can and shut it off. If there is a leak, the pressure will drop.
