2016 6.7 Ford Shuttering

[Smokinrebel]

I just got a new work truck about month ago. 2016 6.7 scorpion. I have 5800 Miles on it, and last night I was driving home and truck started shuttering. At first I only felt it, truck started bucking bad. I turned radio down some and it quit. I started to accelerate again, and it started back. Sounded like bad knock in motor and truck started bucking. It ended up doing in 3 times in about a mile or so. I was running roughly 40-50 MPH in 5-6 gear. The second time I manually down shifted from 6-5 and it stopped briefly. Then it did it again in 5th. Drove another 20 miles or so and it never did it again. Nothing on way to work this morning either.

Never had this issue in my 2011 6.7, any ideas?

Thanks
