Man im having the same problem as you on my 97 eclipse rs 2.0 . Its driving me crazy it will shut off and turn back on if im moving down the road. iv done the same replaced all but fuel pump but i looked at it and made sure its working right. I keep being told it could be the brain so im going to spend the money to replace my computer sometime in the next week or two. I will re-post if it fixes it or if you find out whats up with it let me know please!! P.S. Dont mess with the VSS sensor lol
