That was the random timing retarding tcs issue. This is the no fuel pressure, battey not charging then suddenly its fine problem. It happened in 2007 at the Dyno, but hen I broke 3rd gear. After the rossler was installed it was gone. Then it started happening again while I was waiting in line at trails. Luckily I had a fuel cell to pick up the slack or else I would have never got my 10 second pass.
