While using the Multimeter to determine if the gas valve coils were getting voltage during the lighting process I moved the contacts on the two wire coil and noticed that the coil would activate sporadically. As it turned out the coil had a loose connection which would contact while cool and then lose contact when the coil warmed up.
This was a tricky issue to diagnose and am now waiting for a new coil to finish the repair.
I now have an almost complete set of spare parts for electrical issues and got them at a nice price. I will keep them in the event that I might need some of them in the future.
The repair would have been easy and very straight forward thanks to this website if the actual problem hadn't been the crazy heat related bad connection in the coil. Since the flame would light during startup the coils seemed to me to be good. Actually finding a weird issue is the sort of thing I find to be the fun part of repairing things.
Thanks Parts Select ! !

After some research and diagnosis (checking connections, amperage flo ... Read more w on each electriical part, etc.) I determined that the two coils were faulty. I ordered parts and replaced them (easy to do) and it worked again, for another few loads. Then nothing worked. The coil did not get hot and I did not hear the clicking sound that initiates current flow to the ignitor through the coils.
I checked the coils and ignitor again, they were fine. Frustrated, I called in a repairman to diagnose the problem. $55 and 15 min later he narrowed it down to the High Limit Thermostat. To demonstrate he bypassed the thermostat by directly connecting the two leads together and the ignitor fired right up.
His price to replace the thermostat? $45 part plus $130 labor. I bought the thermostat online for less than half his parts cost and the labor took me 5 minutes. Simply unscrew the small screws with a small socket set or nutdriver and replace the thermostat. Just two connectors, real simple.
All in all it was very easy to replace the parts, just tricky to diagnose unless you are good with electrical work.
