Motor stalls when I hit a bump. It can emediately be started back up. Cannot reproduce when sitting still. Problem started out as a once a month thing and now does it multiple times a day.

Any suggestions??????????????

 

Could be bad ground at the battery, or ignition switch. How sever bump causes the stoppage. will it start instantly. It only takes a momentary disruption to cause ignition failure. Also coil wire looseness or any other electrical corrosion can cause the problem.
Check your fuses for firmness.
