I had this happen to me at the track. Sounds similar, but my car never came back to normal so it could be a totally different issue. You really need a code reader if possible to help figure out the problem. I used my Cobb accessport. My code was a boost leak. A waste gate was stuck open and the turbos seized. My turbos and other stuff were all replaced under the factory warranty. Could your waste gate have been stuck open for a while then somehow started working again? I don't know.
