If it was in the 04 duramax in your sig most likely chaffed harness at fuel injection control module or broken wire to either of the two rearmost injectors on passenger side. Computer sees a momentary fault and will shut down a full bank of injectors until ignition is cycled. Broken inj wires will leave a code, shorted wires at ficm will not always.
