Why does your car stop after putting it in reverse?
This can stem from electrical problems. It is hard to diagnose from so little data. But giving the problem, if it does this going from Neutral to other gears as well, then it is most likely a problem with your transmission or torque converter fluid pressure being to high. It can also be caused from an exceeding low engine idle, whos torque may not be enough to keep running when the trans applies pressure via the torque converter. It is advised to have it looked at by a licensed repair shop before costly damage is done.
