Thanks for everyone's input. It was the #5 sparkplug. I'm looking at it right now, and don't see anything wrong with it, but everything is fine now that I changed it.

Exact same thing here. That was the first problem the after a few more miles the GM wires crapped out. From heat? Had two break internally. TSP recommended MSD 8.5 for LTs. Been very pleased with mine so far.
Then had the same problem come up about two weeks later, #3 plug. Congrats, you got out on an easy fix and only came out losing a buck.
