My neighbor across the street owns a 2004 F250 with the diesel engine. She says the truck loses power and stutters on

Did you ever experience anything like that?


No. When I had problems it just quit running.

However, his symptoms sound like fuel starvation. I 've heard of
similar problems in a in a diesel powered boat when the fuel filters
are clogged.
