Really reasonable idea, Rusty.  I only make the crack about PP to see if you were reading...:0)
The local Advance has the plugs in stock, but Thanks,

Now, here are the pestering nagging questions:  Why would relatively new plugs fail when given the total load?  Why would both plugs fail at the same
time?   Is there something going on that is being overlooked?  Has anybody
else ever seen this happen?  (Ed/ Eddie, are you there?)  Did this happen because I'm so close to 2R4?

 
Hey, don't try to lay this on me :-)     (2R4 is my home airport)
 
The real test would be to put the plugs back in, and see if it still fails.  I would be worried that there was a broken wire going to the coil.  I'm not familiar with the second gen coils, but I assume there's power, or ground, or something that can take out the coil.  I would run it briefly as is, and make sure it's still OK, then put the plugs you just took out in, and run it again.  I would make every effort not to touch any wiring other than the plug wires.  If that's bad, I would put the new plugs back in, and try again, still without touching any other wires.  That test will give you a pretty good idea if it's really the plugs.  
 
It does seem hard to believe that the plugs could both be bad, unless maybe they missed you, and died of loneliness :-)
 
BTW, I know you're short on time in town, and I think I have one new set of plugs at the hanger.  If you need them, let me know and we can meet somewhere.  
 
Good luck,
Rusty
