significant leak somewhere, probably in the air bag system, or in the brakes.

for the brakes front and rear (two needles). If you shut down, both of those
should hold air for a significant amount of time. If they do, then the problem
is elsewhere.

valve was actually coming apart. Point, though, is that one way or another
shutting down when you have full air should show a symptom somewhere.
