Quirk or not? Kirby/Herb...

A few days ago I let the hopper on the 640 run out pellets. When I noticed I immediately added pellets. Seeing as though the igniter was past the 5 minute mark, I assume it was off. The pellets never did re-ignite but instead turned to a smoldering dirty smoke. Because I was pretty close to the end of my cook and I had company, I finished in the oven.
So, the next time I started my pit (of course after cleaning the firepot and unplugging and then plugging in again) my igniter did not start the pellets. I then did a manual start (never had to do one of those in 4 years) and had a successful cook. At that point I became a little concerned that maybe the igniter was going to become a problem.
This morning I went through the normal startup procedure and all is well. Finally getting to my question...does this sound like a normal reaction from my admitted mental mistake by the programed start up procedure, or is it possible that maybe I have initiated a problem in the future and should start thinking about buying an igniter for that (un)eventful day?
