Wow. Like you and your friends, I'm stumped. Keep in mind, because I'm not there, the questions may sound elementry or stupid, but I have to ask anyway. Is there any chance of the boot on a plug arcing? Was the crank sensor checked?
What is most interesting to me is that it hasn't set a misfire code. I need to think. I have a feeling this one is going to drive me crazy too. Also, realizing what all you have done, the above questions may seem stupid, but I have seen it happen before, and I have seen good mechanics not even think of them because when the plug is out and grounded, electricity will always take the easiest way out.
