Sounds like the compressor is working as it is trying to pump up the system then once at proper height it will vent off. Sounds like we may have a leak. While the compressor is on listen for any air from each wheel. Also while it is on lift up and push down on each corner of the suspension to see if you hear any air indicating a shock is leaking. Let me know.
