I've been through the air suspension woes with mine. It was intermittant and ended up being the air bags were dry rotted.

One thing I've wondered about is condensation and how the compressor system handles that. It could be an issue with freezing if condensate accumulated in the lines or valves.

Keep an eye on it, if you start noticing your compressor cycling for no reason then it's time to get it checked out. It's a lot easier to replace the air bags when needed, then to burn up a compressor by waiting too long.
