Mine did the same thing last summer. 100*+,80 - 90 mph. Ran fine but would die and be hard to start (learned I had to cycle the key). I'm leaning towards the fuel vaporizing theory because I didn't do anything with the filter and it was fine when I wasn't running hard in hot weather. I'll be watching this thread to see what I can learn.
