Hi all

Am doing long commutes with my 82 300SD (job transfer). Filled up before I left for home on Friday. Driving from south of Fort Wayne, In to Watertown, Wi. About Chicago, I seemed to notice a bit of a loss of power. Did not get any worse. When I got to Milwaukee, climbing the hill past Rte 100, I really noticed the difference and the car would not go above 60 up the hill, but seemed ok the rest of the way home (A total of about 370 miles). The car sat over the weekend. Filled up Monday, drove back today. Everything was fine till I hit Chicago again (sorry, must go through Chicago), and I noticed the loss of power again. At Rte 30 in Indiana, I pulled off Rte 65 and topped up the tank. Jiggled the plastic filter around. Drove off, full power, buried the speedo as a test further down the road. After an hour or so, started loosing power again. Could not get her to 65 on a hill, but could on flatland. Got to where I was going. A few hours later, took her for a spin. Seems fine again.

Are these the symptoms of a fuel filter starting to plug up? Or what else could it be?

Thanks
