This morning my wife was driving up a hill to work and she said that my "truck surged a few times then lost all power and when she tried to push the pedal down it just chugged a little and a lot of thick black smoke came out of the tail pipe" after she pulled to the side of the road put it in park and called me. Then without shuting the truck off she put it back in gear and drove away like normal.

What do you guys think iot could be?

fuel filter....?

had mine do that once ... turned out to be a bad Juice unit
