Sounds like a plug gap issue to me. Boost is blowing the spark out from too wide of gap.

Eventually they found out the camshaft had been damaged, a lobe had flaked off. Service guy said he hadn't seen that happen before though.

No, I haven't noticed any increased engine noise -- although a broken cam lobe is a bit scary! Definitely sounds like a freak occurrence, but I'll keep it in mind if I need to continue troubleshooting. Thank you.

Thanks, King. I'm going to try the NGK LTR6BHX (90495) Ruthenium plugs for my next event, but I'll check the gap on all of the plugs I remove.
