having issues with a/c full on r134 works sometimes perfect blows cold.but just quits not getting any power to compressor then will just start working. when working pressures are proper. tried to jump power to red wire going into compressor ran for maybe 30 seconds and quit again.but on way home ran perfect for about 30 mins then quit working again...

Keep in mind that Dec05 production and later are different from earlier cars.
Does it just loose power to the compressor while the pressures are normal?

never been able to check on machine when it just quits.its not freezing up just quits working a/c shows green but not cooling at all may start working in few minutes or days later.

My be just low on refrigerant (very small leak). It will work OK on idle but at higher rpm the pressure on low side may be getting too low and the ECU will shut it off. Try to recharge and shoot some dye into the system at the same time.
