Hello I have a 92 up 4.0L straight 6. That is cutting off on me while I’m driving. It only cuts off after driving non stop for a long period of time at a constant speed and only cuts off while I’m coming to a stop. I changed out the fuel pump and still have the problem. Checked out all my fuel line and nothing is dry rotted or cracked. I’m stumped and was wonder what yall got in mind for me to try next.
