you just sent a chill down my spine.obviously it's electrical.the first thing i thought of was main loom deteriorating but then i noticed that you have the V12 engine so i figured no way that was usually for the six cylinder models.then , while i'm writing this i realize that the V12 is like two sixes together , so maybe it is the wiring harness.klimas and the like don't apply to our model so i would suggest you check the wires and look for cracks in the wire sheathing or missing insulation altogether.good luck, keep us informed.
