This sounds like an odd question, at least to myself, but I have been wondering if a bad or failing ignition component such as the distributor, ICM, or the coil can act up or show symptoms of failure during certain temperature conditions.

I have been running the truck without a thermostat while doing the cooling system flush. I don't drive it and it rarely gets over 160 degrees. Should be completing the suggested 3-6 hour "flush run"this weekend. I will be replacing all hoses and putting in a new thermostat at that time.
