Purchased a 2004 F250 6.0 Diesel F4 less than a week ago with 4500 miles. Two days after purchase the truck starts stalling out or losing its power at intermittent times. The troublelight on the dashboard indicating water in the fuel comes on and the engine basically dies. It's quite dangerous pulling into fast moving traffic in this condition. Drained the in line filter and no evidence of water was present. The dealership says it's probably a faulty sensor since they've had several in with the same problem. They are doing diagnostics on it on Monday. Is this a simple fix or is there more problems on the horizon? Are other 2004 Ford 6.0 F250 diesel owners experiencing similar problems?
