Hi Dusty
sounds like leaking O-rings

agree, leaking o-rings or valve stem core leaking

Take an old hand pump spray bottle, like the kind used to dispense bathroom cleaners, and fill it with water and a generous squirt of dish detergent. Shake the mixture up, pump up your suspension and spray a few good squirts on every joint that you can reach in the air system. If there is a leak the mixture will begin to bubble up and foam at that point.
I realize that you probably will not be able to easily access all the hoses and joints but the likelihood is that the most moved joints are the culprit and they are the most accessible.
I work with various pressure vessels and this is a very common technique to find slow leaks.

It is best not to leave the dried dish soap on the bike, but it rinses off easily with water, taking dirt and grime with it. (Leaves your hands soft too)
