Narrative:
#2 engine failed and was noticed spooling down by both captain and first officer. Speed started to dissipate, so a request to descend was approved to FL240. Captain and flight engineer conducted the engine shutdown checklist during which time it was determined that the #2 engine fuel valve shutoff switch was in the closed position. After realizing the cause for the failure, and determining normal engine parameters, and in-flight start was accomplished, and the flight continued to the destination routinely. The fuel valve shutoff switch had been inadvertently closed by me, I believe, while rotating tank boost pressure light caps to the dim night position. A possible corrective action would be to install more positive guarded caps over the shutoff valve switches. I, in the future will be much more guarded, when I move light caps of other switches in proximity to the engine fuel shutoff switches.
