I thought it was bad fuel. Changed filters and would run ok for about 3 miles. Changed water separator again same thing. Drained tank put fresh fuel in it no change. Anyone have any ideas?
 
I love these super-descriptive posts.

"hey my truck isn't running right, whats wrong with it?"
 
I'm going to go out on a limb here and say something is not right. Solution... repair it.
 
First it is not mine.It is an 03 f250 no codes. No smoke.Run great for 3 to 7 miles then no power like it's running out Fuel. They changed filters 3 time still the same. I had asked them if alt was charging and batteries good, yes they checked grounds ok.
