I can find no where for the air to leak out. It seems like it has to
be at the top of the tank, above the plug that I remove to drain out
the excess water. I don't think that it is the drain plug because as
soon as it gets below the water level if there was any leak, it would
then be water, and I dont see any wet spots.

Any Ideas would be appreciated.

If your tank is a bladderless, there is nothing wrong with it. The air
isn't leaking out, it is being absorbed in the water. A few months is
about the right time. You do have a problem with the snifter valve or
other means that should be adding a shot of air every time the pump
starts.

If it is a bladder tank, your bladder is broken.

The simple fix in both cases is to simply replace the tank with a
bladder type. Cost of tank is reasonable and installation easy for
average homeowner.
