Did You send that log to Alltrax?
I think you may be having issues with that TPS to MCOR adapter, if You notice in your logs the HPD flag is dropping and the cart is going into regen with 100% throttle.
In the Alltrax software go to:
Tools->Options
Check the box: "Allow edit of throttle types"
Then on the Throttle Settings Tab,
uncheck "High Pedal Disable".
If that takes care of the problem, You will need to bypass that adapter.
