A/C is fine, then just starts blowing hot air

2004 9-5 Linear. 101K. A/C turned on to Auto, Both drivers and passenger climate temps set at 70 degrees F, cool air is being discharged on dash vents. Fan modulates with temp rise and fall. All is fine for maybe 20 mins, sometime as long as an hour. Then it begins to feel warm in the cabin....check the dash vents- drivers side cool, center is slightly warm, passenger dash duct is discharging hot air as is the rear seat center duct.
This behavior has persisted over two years, visited dealership 2x's with the result: checked it all out-could find no problems-works fine.
I've reset the A/C from the front control panel, and it has had no effect.
This problem is driving me nuts...any diagnostic suggestions?
I've only seen this behavior in the summer with the A/C..never with the heater in the winter.
One could argue that it is the climate control trying to adjust each 'side' to meet different temperatures-but the temperature settings are identical.
Thanks for any suggestions....
