TPS will not cause that issue.
It could be a loose connection disconnecting due to the vibration at 6000rpm. I had a similar thing years ago on a 400 four Honda, ran fine and sometimes under acceleration over 7000 it would cause the kill switch connector to come apart, then when revs died it started again. Frighting when it happened overtaking a truck. It was only when I started pulling connectors apart I discovered it,
Check all the connection under the tank for corrosion and the left side panel.
Do not rule out the Regulator/Rectifier, 6000 rpm is 1000rpm above the max output limit of the Rectifier/Regulator which sounds like the Ignitor is shutting down due to excessive voltage.
