I have a 2008 F350 Super Duty diesel. I also had a problem on 2 occasions where the truck would stall under power. After reading and digging in this forum, I found that there may be a wire pinched in the steering column for the cruise control I was using at the time. I stopped using the cruise control and have not had a repeat of this problem in the 3 years since! Not worth the hassle to pull the steering wheel to get to it.
