Neil Lennon’s men were trailing 2-0 to a first-half brace from Eamonn Brophy when the power went out at the stadium around the 50th minute.
There was a 15 minute delay before the players emerged from the tunnel again and the game restarted.
The game played on for around 15 minutes before the lights went out for a second time as the whole ground descended into darkness.
Referee Craig Thomson gave it one last chance to finish, which it did with Killie adding a third through Greg Stewart.
