Hi everybody. This is my first post on the forum. The problem I have is with my dads 91 sahara. It is stock with a 6 cylinder. It seems the keyed power is going away at random. It will not let anything work except the lights. Then without doing anything, not even being around it, the power comes back. Radio plays, buzzer sounds, everything. Most of the time it will turn over and start. At times it will die completly the second you put it in gear. Other times it wont die. When it dies everything goes dead again. You can wait 10 minutes or maybe an hour and it is back again. I am an electrician so I backfed the keyed power on the fuse block. Everything works fine. Starts with the key and everything is fine. You cant shut it off with the key since it is going around the key switch. What is there that would cause the keyed power to come and go? Any ideas?
