Use the tire gauge and don't rely on what the installed gauge is telling you this time. It might be stuck/giving you an erroneous reading.
In the original post, it's indicated that the tank has 37 PSI dry. I'm assuming this means that it's already been checked with a tire gauge.

I think the blue control box which says "Goulds" may be the culprit. First, check to make sure all the connections are secure, particularly the wires going from the control box to the well. You should be able to (first turn the power off then) remove the capacitor from this box and take it to a pump dealer who can test it. If it's bad, it's a simple matter of replacing the capacitor. If it's not bad, you might be faced with replacement of the pump.

Replacement of the pump can be done by yourself & a helper, but it takes some ingenuity to safely remove the pump from the well and put a new one in without dropping the pump in the well. 500 feet of 1-1/2" galvanized pipe full of water with a pump hanging off the bottom is VERY heavy. That's 45 gallons -- 360 lbs -- just of water, plus whatever the pump and pipe weighs. If you do accidentally drop the pump into the well, things get really interesting and potentially very expensive.
