The pump you have may just have a hard time reaching 65 PSI. Loosen the big adjustment screw (3/8 nut driver) in the pressure switch until it shuts off at 60 PSI. (probably about 2 or 3 rounds) Turn power off before adjusting this screw. It is very close to the 240 volt points. Don't get shocked. After this adjustment is done, see where your pump starts. Make sure you have about 2 to 5 PSI less air charge in the tank than the pump start pressure.
