I had something similar happen to me when I had about 6k miles on my truck. I was driving down the highway at about 70 mph and lost all boost and power, check engine light began to flash on and off, and I barely got over to the side of the road. I shut off the truck and turned it back on and the check engine light was solid at that point & I had no power in any of the gears. My truck would not go past 35 mph and my rpm would not go above 2500 and that was with the throttle all the way down. To make a long story short they ended up replacing the PCM harness due faulty wiring. Before that I had my CEL come on 2 times w/different codes. I know have 8k miles and so far I can't complain.
