Loss of power
I have a 2000 F-250 with 230,000 miles. I was driving down the highway last night and when going up a small hill, the ruck hesitated, just for a second, then seemed to run fine. I went another 15-20 miles and was climbing another hill and the truck suddenly lost power. I got to the shoulder, and stopped, I put the truck in park, and whn I pushed the throttle it sputtered and was blowing blue or white smoke. I then turned the truck off to see if it would restart, it started fine, but still ran rough. I was about a mile from my exit, so I limped it the rest of the way, it did pick up speed, but it still did not run right. I had the truck towed home, it was about three hours later, when I got home, the truck started and ran fine. This morning, I went out and it started fine. I carry a cam sensor in the glove box, because we have ran into problems with them on our trucks at work, so I changed the cam sensor. I haven't changed the fuel filter yet, but I have pulled it out and looked at it, it doesn't look like anything out of the ordinary. I have had the truck for about four years and put about 50,000 miles on it, and have had no problems. As far as I know everything is original on the truck. Any suggestions on where to go next would be greatly appreciated.
