Breaking-up/sputtering under load

Did a track day at NJMP/Thunderbolt yesterday, which was great fun until the
bike started acting up (which, unfortuantely, was mid-way through second session).

The bike feels like it's missing in various parts of the RPM range, which
changes slightly depending on which gear the bike is in. It often misses between
5 and 6k, then again between 8 and 9k. Won't climb above 7k in top gear. Seems
to run fine at idle and through rev range when parked. Only slight blip between
5-6k in first gear.

Has something similar happened before to anyone here? Any ideas where I should
