Normally I would suspect tires and/or wheels, especially as I had been on some bad roads. But this seemed to happen just as I noticed an occasional jolt which seemed to come from the drive train under heavy high speed acceleration. Sometimes it is a single sort of hitch and sometimes a sort of jerk-jerk. There is no sound associated with any of this.

Thoughts?
I'd check wheel balance and then see if the jolt is still present.
