Good question, Patrol! And you made me think that this might even be a bad battery problem, as our bikes seem to be very succeptable to any weakness in the system. A weak electrical system will usually give you symptoms at lower rpm's first. From everything that the original poster described, it just sounds electrical to me. There may be a corroded connection that is just bad enough to stop a very weak current (ie: low rpm/voltage/current). These types of problems can be very difficult to diagnose (especially over the internet!) because they are intermittant, so he can not just check for a lack of spark when it happens. Of couse he could just have a tank full of crud, but again, the OP said that he has checked this out to his satisfaction.
Although, I once had a very similar problem with my DRZ, and it turned out to be the placement of the kill switch. I found that as I was riding it and crawling all over the bike, I would hit the switch with my wrist just enough to kill the motor.
Anyway, the problem as described here, definately warrants re-checking everything that was already checked. I do not know if the OP had to pay a dealer or a mechanic to perform those checks, but the fuel filters and carbs are definate suspects *if* they are still not perfect.
