So....the saga continues.
Finally decided to take the chance and use the truck last week for my morning 20 mile commute, mostly highway. Cruised well on the way in at 55mph with only some minor wandering in the steering to make things interesting. Used it again to run out and grab lunch with again, no issues. On the way home, I left the city, headed directly up and over the bridge, and then immediately had loss in power and had to pull off. The loss only seemed to come on when the was load on the engine. With the clutch depressed, i could blip the RPMs with no issue for the most part. The minute I tried to move forward at any speed in gear, the motor would bog down and even cut out completely some times. Tried a few times to get her moving and limp my way home with no success and had to end up getting flatbedded home. My initial thought is fuel but anyone have any ideas and where to look?
