Default AC Shuts Down After 20min?

I'm looking to solve a problem that I've had for about 1yr. First, I have a supercharged 402 ... wanted to get that out of the way up front. Once my car heats up, the air shuts off and the runs off and on.

When I lived in CA it wasn't much of an issue. But, now that I'm in Austin, TX it's a hassle.

Any advice/thoughts?

If your car's an 05 it was overcharged with r134 from the factory. I just had mine fixed a couple of weeks ago.

Check out post 25 on this thread.

I printed the post for my dealer and they found the document and did what it specifies and I've not had a problem since.

What temp is your car running? I had a similar problem when the car would get up to around 230. I had to install a larger radiator.

AC may be overcharged. Happened to me with a turbo install on my G35 coupe.

Hook up some AC pressure gagues to see what is going on. Not all systems were over charged.
