[E350wcvan]

I'm a first time diesel owner and a wheelchair user, so I'm not really looking for do-it-yourself answers as much as I am in advice on how to respond to Ford dealer service.

About a month ago I bought an '03 E350 Super Duty 7.3 van, with only 8,600 miles, equipped with everything to make it wheelchair accessible. It ran fine for about a week, then began to sputter or stutter everytime we drove it a few miles.

The dealer has changed a fuel filter, a solenoid and valve, fuel pump (twice!), and the fuel water seperator. Nothing fixed the problem. So we had the tank dropped and cleaned where they found what seemed to be shredded up paper mixed in the fuel. It was a mess, but they cleaned and replaced the tank. We drove it about 90 miles afterwards and it started doing the same thing. Now they say an in-line filter may need to be changed a few times to get all the gunk out. Does that sound right to anyone? I keep wondering if it's an electrical problem, but the Ford dealer here claims to have a good diesel man on staff.

Right now I'm just puzzled and looking for advice. I rely on this transportation for my job and in fact I bought the van because of the solid reputation of the 7.3 powerstroke.

Thanks for all your advice and I apologize for the length of the post...
