I'm chasing a similar, but not identical, situation. Swapping the coil is a pretty simple test and easy to do. Saabina would say check your temp sensor in the middle of the intake manifold for proper resistances. I would add that you may have a fuel injector acting up...or possibly an O2 Sensor. Things that fail when they heat up is a fairly normal pattern. Tracking them down can be tricky. Having parts to swap helps. Too bad your not picking up a Check Engine Light. That might help.
