The problem seems to be on the control side. I am an HVACR technician and I'm very failure with gages and pressures. My first instinct was that the system was under charged so I recovered the refrigerant , pulled a vacuum, and weighed in a new charge. Unfortunately this did not fix the issue. The problem only seems to happen when the inside of the car is hot from sitting in the sun. Once the inside cools off from having the windows down the A.c works fine.
