The only anomaly that I see in the tune is that you have your full throttle shift speed for pattern B going into 6th set to 0. I know that shouldn't affect TUTD shifting into 5th, but weird things can happen if you have some conflicting parameters in parts of the tranny tune.
Other than that, maybe the trans is going into over-temp mode? You could try temporarily raising the full throttle shift RPM for the HOT portion to 8000 or so and see if that cures the issue. If it does, then you have your tranny getting hot, which is an entirely different problem to deal with.
