jim911: A tip I learned the hard way. Pull the gas line off at the tank. Put into a can and watch the fuel run out. On my 52 1/2 ton it would run for a bit then slow and stop. Crud in the tank. Winter and I did not want to pull the tank out. So I rolled a bit of screen door screen up about 3 inches long and just wide enough to make 2 complete wraps. Pushed that up into the tube from the tank and now the crud can not block the out let like it did before. Use good metal screen no plastic for this. Add a clear fuel filter to get the small stuff before the pump. Made all my problems go away. Got 900 miles with no more slow down and stop issues. Might be what you have as well.
