After many years of driving, I also had a problem with the engine shutting down, after approx. 10 to 20 minute ride on my 2009 GG280 TXT. I Couldn't restart engine while warm. There was no spark on the spark plug. When I replace it, the engine runs for about the same time, then it shuts down on its own. I replace the ignition coil with a spare one, the spark plug still has no spark. Then I happen to find your wiring diagram and check the resistances on the ICM connector and notice the problem that the resistance on the BLK/RED wires is 0 Ohm instead of 20.9 Ohm. Both other resistances were very close to the prescribed ones. Member drca, I thank you for providing this schematic because it allowed me to get a quick diagnosis.
