Your belt is climbing right out of your primary on the drag race. In the deep it has resistance and will gear itself down as needed to maintain track speed and never get that high in the primary. Torque stop may help if engine mounts are week, or you have a broken one that needs replacing?

I had the same problem, I tried a torque stop and it didn't seem to help so I went to an 031 belt and haven't blown one yet.

you should check the motor to make sure you did not tweak the crank. This will happen when a belt blows. Also check the clutchs are parallel as well as alignment.

Overshifting....gear taller if you go that fast very often to keep the belt from climbing out of the primary or bottoming in the secondary.

I was also thinking your ctr/ctr could be off for the stock belt? If too close the belt would climb out, If too far apart it would stretch to all beat**** and could break if enough tension was applied when maxxed out?
