It's a Jabsco Par Max 3. There's a pricey replacement, but I think I can take it apart and try to clean it up.

Accumulator problems (and blocked strainers) present different symptoms and your pressure check verifies thats not it. Note: check accumulator bladder pressure when water pressure is released from system.
A downside to many of the fancy new pumps is that the pressure switches are not serviceable and have limited adjustment. You can try to get at as much of it as you can and clean it, but I suspect you will have limited success. The design intent is to force you to buy new one.
The pump
head and
motor are very durable and are unlikely the problem. How old is the pump? Worn
parts on very old or poor condition heads/motors can stick and cause similar behavior, but thats way less common than a bad pressure switch.
The pressure switches are over priced for what they are, but not painfully expensive. I suggest you get 2...one for this
repair and a spare...as the pressure switch will likely fail again.
