I would check your plug wires. You might have a couple which are arcing/shorting at high rpms. Seriously, sometimes just rerouting them/sheathing them a little bit makes a difference.

Good luck.

Yea the clutch could definetaly cause this. One question though: Were you looking at the stock tach and seeing the RPMs jump? Or did you feel it as well?
