You also want to leave instrumentation, lighting, and the blower motor running so there is as little disruption as possible when you hit the kill switch.

Leave power to the "hot in ON" rail, but kill the injectors.
Thats the best idea, and what I did to my car. leaving the goodies running is nice.
