It sure does sound suspicious. I agree that chasing any
possible air leaks would be a priority.
You may have to put a gauge on the pump to see whether the
pressure builds immediately as the pump starts.
These intermittents are tedious to track down and most
techs don't have the time to spend. You're better off
being your own detective sometimes.
