My truck stalled at 45 mph in 4th and seemed like it just shut off. I coasted in gear down to about 35 mph and it took right off no more problems, starts good ,has good power in all gears, all speeds. Any ideas what caused this? The check eng light was on for a few days but its off now. Good fuel pressure . (10-12lbs)98 5 speed 3500, stock except for supper chip , tow safe. Does water in the fuel sometimes cause this? thanks Otis
