Car will “stall” with no warning. Sometimes the car will not start. Pull a wire up leading to the battery, all is good.
Good Greif , how big of a clue do you need . Have the wire fixed and your problem may be fixed .
Yup, congratulations. You found the problem that others have found elusive. So replace that particular cable or severely check it for bad connections or internal faults. Easiest just to replace.
