After several storms, including two tornado warnings, the race restarted at 8:53 p.m. - almost 6 ½ hours later.
The race returned to green flag conditions on Lap 47, with Kyle Busch in the lead followed by Kasey Khane and Hamlin.
During a round of green-flag pit stops, Kahne spun on the exit to pit road and fell a lap down. Kyle Busch also lost a lap when he was penalized for removing equipment from pit road.
Once green flag stops were completed, Paul Menard led the way on Lap 90 followed by Hamlin and Kevin Harvick.
After 100 of 200 laps, Menard continued to lead followed by Jimmie Johnson and Dale Earnhardt Jr.
On Lap 103, Tony Stewart brought his No. 14 Chevrolet to pit road for the first of several trips for a problem with his fuel cell.
Shortly after another round of green-flag stops, Harvick nipped Brian Scott, who then hit Aric Almirola which ignited a 13-car wreck on Lap 145.
On the restart on Lap 154, Greg Biffle took over the lead, followed by Earnhardt, Carl Edwards, Johnson and Matt Kenseth.
During the next four laps, Earnhardt and Biffle traded the lead three times, with Earnhardt got around Biffle on Lap 155 to take the lead for the second time in the race.
