Radon Bubbler losing pressure

My radon Bubbler pressure is set 40/60, and is a 35 gallon tank, and my well pump pressure is set to 40/60 and is 25 gallons. Regardless of the amount of water we use day-to-day, periodically the Bubbler loses pressure, and I have to reset it, as if we lost power. Sometimes it’s multiple days in a row, other times it will go several days without incident. When I reset the pressure in the bubbler/mitigator, the pressure on the well tank does not lower or fluctuate at all. The bubbler has been serviced, and there are no visible/obvious leaks in the plumbing.
