Hey, this same problem just happened to me with my 98 explorer and ya you are right. I was coming home from school and my car went for like 100yds and then the engine made some noise and quit. I put new plugs and plug wires in it as well as a new fuel filter and fuel pump. It has nothing to do with fuel. I took it to a good friend of mine who is a master mechanic and he said my timing chain was broke and labor was gonna cost me 1300 plus 500 worth of parts. I am now wondering if it is smarter to get a new reman. engine. By the way there was a recall for the 98 explorer on timing chains but it ended feb.2005. Good luck man.
