Just wondering why it would only do this when warm?
Really bad misfire, too - sounds like an old Russian tractor, and shudders like a crapping dog's tail.
Anything else I should check before the coil pack? I've done that once before and I remember wishing many unpleasant things on the 'designer' who put the damn thing where it is!

It will more than likely be your coil pack. As with anything electrical, they don't like heat. Essentially, when your motor gets warm/hot the electronics of the coil pack start playing up.
Get yourself a very long extension bar with a 3/8 drive. It will make the job ten times easier. The last coil pack I did took me about 15 minutes.
