My 04 xr6t had similar issues way back , turned out to be the tps , the original throttle position sensors are sh*t , I went to ford and got the upgrade tps and its been perfect ever since

sounds like it over boosted and went into limp mode.

I had this happen to my ba mk2 turned out to be the diaphragm in the waste gate actuator was stuffed. I cut it open and the diaphragm had a hole in it and looked like it had perished due to oil contamination, plus heat from the manifold. You can test for this with an air compressor, just disconnect the signal line from the boost controller and plug it into 15 psi regulated shop air. You shouldn't hear any air leaks and the actuator should move.

As others have mentioned. Sounds like overboost cut out. Something is causing overboost.

Is the car 100 percent stock?
