So I have a 77 scout ii with a 345 v8. It has an issue now that when you crank it up it runs for 30-45 seconds and then cuts off. Sometimes it runs longer and sometimes shorter. It is not carb issue it cuts off like you turned the key off. I can see there is a cable that comes from the steering column down to the harness under the dash. Not sure if that cable could be causing the issue or shorting or if it has nothing to do with the switch. Just seeing if anyone has had this issue before I just start guessing at replacing parts.
