Low pressure is in normal range of about 25-30 or so psi, high pressure though is way high at about 320-350 psi (should be more towards the 220-250 range). Therefore it's either a stuck expansion valve or bad condenser. It works fine for about 2 hours or so but then the high pressure switch cuts off the compressor until the condenser cools. Therefore letting the car sit a few hours and cool down brings down the pressure enough for it to start working again. It is not evaporator freeze up. I should know more by tomorrow, its at the shop and they are replacing the expansion valve.
In 2014 they replaced the condenser after I hit a coyote on the interstate doing 70 mph. Of course the condenser took the brunt of the hit. They should have replaced the expansion valve when replacing the condenser but apparently they didn't. I'm betting that is the entire cause of all this.
