I'm not sure whether anyone else has this issue, but I thought I'd pass it along.

I installed my kill switch about 3 months ago, and I recently discovered that I was turning it back on (the keyswitch) a little too early. When I kill the engine I was used to waiting 2-3 seconds for the engine to come to a stop. With my big diesel, it's pretty obvious when that happens (one can feel the shake). I had already know that if I turned the keyswitch back on prior to the shake, the engine would restart. What I only recently discovered, by using my loging software, is that even after the shake, the engine was still turning slowly for another few seconds (~5 sec). If I return the keyswitch to the on position during this time, the engine doesn't restart, however, it attempts to--in my log (as well as the tachomter), I could see a blip in the rpm where it fueled for a brief period of time attempting to restart.

So the solution is just to wait a little longer before returning the keyswitch to the on position (at least 8 seconds from the time I killed it). I'm not sure if it cost me that much fuel, but I'm sure it was a little.
