Does it still have a stock intercooler? I had this problem once after installing an after market I/C. It was a grounding issue with the I/C and the engine. The overboost switch mounted on the intercooler was cutting out due to bad grounding. I also noticed that it would run fine for a while, but cut out under boost caused by improper mounting of the I/C - the pressure in I/C piping openned the ground connection for the same switch.
One way to quckly check this is to gound the overboost switch by connecting the wire from the overboost switch to ground and try to see if things are ok).
