Power lost on hills
I just towed my horse trailer again to see if it would repeat the no power problem.
Got up one hill o.k. and coming back over the mountain just as before all the power went away. Boost dropped to 10lbs. wouldn't rev over 2500 rpms. Nearly got ***-ended by a freight truck pulling the same hill.
Called the service manager and he says. Well we got to duplicate it to find it so now I've got to hook up my flatbed gooseneck and load it to simulate the horse trailer weight.
This is B.S. I am not making this up.
Is there really hope that a judge will make the a$$holes at ford buy this heap back?
Truck towed flawlessly until the pcm re-flash........

6.4 08 SD Having Power Loss Issues
I'm having a similar problem with my truck, just hit 36000 miles on a 2300 mile trip from Utah to Quebec Canada. I hit the gas pedal to pass a car going 70 mph and the truck started to shake and lose power. I was thinking injector issues but could also we a fuel supply issue? I had both fuel filters replaced by ford just before going on the trip. Before I started having issues I was getting 16.7 mpg and then I got 12.3 mpg once I started having problems. It also seems to go through REGEN more frequently? Any suggestions? Do you think I can chance driving it back to Utah next week before I have it looked at?

On two separate occasions my '08 SD has tripped off the cruise control, lost power and started bucking like a mule. It wouldn't accelerate over 40mph regardless of throttle position. The boost guage would rise slightly and then drop rapidly with the power loss, but no check engine lights would trip. The truck has 40k on it, had plenty of fresh fuel, is up to date on filters & maintenance, had Ford cetane booster in it, etc. After nursing it to a safe spot I shut the engine off and restarted it and the problem was gone and hasn't returned again. It coincidently happenend while heading in to a stiff head wind. My area dealerships have no clue, but are more than happy to check it out (drive it down the road at a price of $85.00 / hour) in the attemot to duplicate it. Any suggestions? I have better things to spend money on.

but I'm not positive on that.
