The delay didn't dampen Biffle's spirits however and as soon as racing resumed he quickly re-established his lead over third place starter Kyle Busch and the second of the Roush-Fenway machines of Carl Edwards. After two more quick caution periods Edwards moved into second spot and seemed content to sit about one second of Biffle's rear bumper as a round of green flag pitstops approached just shy of the lap 150 mark.
When Biffle pitted on lap 148 he conceded the lead for the first time under green flag conditions all day and while he soon regained it as the order cycled through Edwards was able to pass him for the lead for good on lap 170. Now it was Edwards' turn to pull away as Biffle, hampered by alternator problems, began to struggle.
Kyle Busch moved into second spot on lap 185 and slowly worked his way onto Edwards' rear bumper as a second round of green flag stops began on lap 225. It was now that Busch's #18 Joe Gibbs team came into their own, turning Busch's car around in under 13 seconds and handing him the lead when the order shuffled out.
Busch didn't get a chance to showcase his new lead for long though as the fifth and final caution period of the day waved for debris on lap 242, bringing Edwards, Biffle, Matt Kenseth, Jeff Gordon and the rest of the leaders back onto Busch's rear bumper. But Busch needn't have worried for when the green flag dropped on lap 247 Busch simply drove away again.
Edwards did his best to stay within striking distance of the leader as the race entered its final 100 miles, running directly behind Busch on the track as the final round of stops approached. With no caution period to help them it was squarely down to the crews once again when the stops finally took place between laps 315 and 325 with Busch's crew again proving themselves to be a cut above the rest as they serviced Busch's car in less than 13 seconds for the second straight stop to hand him a three second lead by the time the order sorted itself out.
