Over the last two track days (Saturday and this afternoon) my car has started cutting out. It's fine on the out lap and the first two or three hot laps but then gradually starts cutting out and I end up parking it about half way through the session. By the end of today I made it two and a half laps and barely managed to get it back to the pits. It didn't show a CEL until the last session and that was a flashing P0300 in Track Addict - but that code is not currently stored and did not show up by the time I got home to read the code with my computer. The problem is, it drove home just fine and I can wring it out on the street and not replicate the problem. So far this is only occurring on track and after the car has some heat in it. At this point I don't think it will do any good to take it to a dealer. How in the world do I troubleshoot this?
