2003 tahoe a/c problem

I agree with Dink. Sounds like a fan issue. Setting still, no air flows through the coil but does just fine when moving. I also had a similar problem a few years back with a 99 Sierra. The compressor was "coming apart" inside and sending metal filings to my orifice valve, expansion valve whatever you call it. The filings would of course clog the thing up and the pressure would build to a point that when I wasn't moving, the compressor would cut off. When I was moving it worked just fine.
But check the fan first.
