Got a 2000 Pete 378 with a N14 red top Cummins. Today when I was coming back empty from dropping off the backhoe, it would not go faster than 50MPH. It would accelerate fine with plenty of power up to 2000 RPM until 9th gear. In 9th gear, as soon as it hit 50MPH, it seemed as though it was speed governed and everything would die until the speed dropped off and then it would power up again. The RPM's at 50MPH in 9th gear was about 1500. I tried to drive in 10th, but as soon as the speed hit 50MPH (1200 RPM in 10th) it hit the wall again, would cut off until the speed dropped and then it would fire up again until it hit 50.
I've called around to some shops that can plug into the computer next week but thought I'd check here first to see if anyone has had a similar issue and offer some suggestions.
The worst part was this as a long haul (for me) thru Friday night madness on I35 all the way thru Dallas to the OK border where the shop is.
