Given that it wouldn't start until you cycled the key; is it possible you tripped the 'drop sensor'? If a 900 is dropped or crashes, the engine will shut off. If the engine is already off, it won't start. It won't start or restart until the key is cycled. I don't know how that system works, but, since the wire goes back to the ECU, is it possible it's inside the ECU (the behavior is crank-no-fire when tripped) that kills the engine and keeps it from restarting until cycled? (Seems likely). That may have been your issue. Applying a load to that circuit may have made the ECU think the drop sensor was tripped.
Just an educated guess is all. I don't have any knowledge that this is what happened; just something to think about.
