87 jeep shuts off while driving

While driving down the rode my 87 jeep just shuts off and sometimes it starts right back up and sometimes it takes days. Does anyone have any ideas? I think its an electrical problem. Thanks

sounds like your electronic ignition module located under the windshield wiper reservior mine unbolts from the the front driver side wheel well , its verry easy to remove look in the wheel well and you will see three small bolt heads in a triangle shape .. take it off and take it to auto zone they will test it and it costs $57 if its bad for a new one, good luck:2cents:
