Honestly, I had this exact problem, it turned out to be that I forgot to put the battery tie down back on the battery after cleaning out under it, and it was moving forward and shorting out against the cross frame, killing the car. it wasnt till I did a burnout for some guys and they said they saw sparks coming out from under my car that it dawned on me :rolleyes: dummy I know heh, start there.
