Review Log files 2011 turbo GMC keep shutting off @ high speed

tur1500.hpt Hi
recently I take the car for a tuner and tuned a 2011 Sierra 1500 Truck stock 6.0 bottom with a gaped ring, BTR cam, 80 lb with stock fuel system VSR7875 turbocharger + snow meth
the car runs smoothly and makes 600 hp @ 11 PSI
without any issues during the dyno.

after that, I get issues with the car shutting off while driving on the highway @ 120mph .unfortunately that run I didn't get any record.

I attach the tune and some logs I do if someone can review and advises me about what thing I need to look for.

Maybe put a time stamp where you feel it.

It would also be a good idea to get a wideband logging. I didn't see one in the log.
