An update (sorta)....
Matt (Mlessard) is lending me an ignitor and it should be here this week. I will run her up and down my street until she it starts acting up and then swap the ignitor. That will either prove or eliminate this part from the equation.
If it is the ignitor, then I will have to take it to the dealer where hopefully invoking Service Bulletin #52 gets it replaced for free. If it's not the ignitor, then I will further troubleshoot it down to the root cause.
