The first time this happened was after I washed the motor. I was driving home and it died in the middle of the road. Ever since then I have been trying to figure out what is wrong. Sometimes it won't even start after driving it but mostly it dies while driving it. I thought it might be the fuel pump so I changed that the other day but it is still acting up. I have to figure this out. It is a 1994 Mazda 626. If you can help at all please do!
