Hello, Eddie here, it's likely the compressor clutch, they get hot and then develop an open circuit in them. Verify power to the compressor clutch when it does act up. there is a BLACK/YELLOW wire going to the compressor clutch. only one wire, it grounds through the body of the compressor. Check it with a volt meter or test light, if it has power to it when it acts up. Then it will need a compressor clutch. I'd go ahead and put another compressor on it. As it's likely original and just putting a clutch on a 13 year old compressor is probably not a good idea. Let me know what you find there.
Alright, there is a compressor relay. Is it automatic climate control? or manual?
Alright, see if you have power to the compressor clutch when it acts up and start there in my opinion. Let me know what you find there. I do have the wiring diagrams for Automatic temp control. Does it have navigation or no?
Alright, here is the wiring diagram, make sure when it acts up that fuse 66 (10 amp) is still powered up as well. And check power to that compressor clutch. Let me know what you find there.

The A/C relay is in this diagram. when it acts up, pull the relay and see if you have power to TWO pins in the relay socket. BLACK/RED should be hot and LIGHT/GREEN should be hot. per the diagram.
I believe you'll find the culprit tracing that circuit if the compressor loses power when it acts up.
