Kurt Busch had plenty of gas this time.

After running out of fuel while leading eight laps from the end a week earlier in Richmond, Busch dominated Sunday's NASCAR Nextel Cup race, completing a sweep of the 2004 events at New Hampshire International Speedway and coming away tied with Dale Earnhardt Jr. for the lead after the first race of the new 10-man, 10-race championship showdown.

"Well, number one is in the books, but there's still an awful lot of work to do," Busch said after leading 155 of the 300 laps on the 1.058-mile oval in the Sylvania 300.

Busch was just as strong late in the July race here when he won easily, solidifying his spot in the top 10 in the same No. 97 Roush Racing Ford that he drove on Sunday. The win was the third of the season and 11th of his career for Busch, who began the day seventh in the points standings.

"This car was awesome. It was real tough," he said, laughing. "We had to take the car cover off and throw [the car] back out on the track."

Matt Kenseth, the 2003 series champion, was second, crossing the finish line 2.488-seconds -- about 20 car lengths -- behind his Roush Racing teammate.

"I knew we probably weren't going to catch him," Kenseth said. "Kurt had a great car and was getting through the center of the corner really fast. I tried to keep up with him as long as I could.

"We were set up a little different than Kurt. We couldn't do anything with him, but I'm pretty happy," added the driver who won the Cup championship last year in a relatively boring runaway that helped NASCAR in its decision to change the points format.

Team owner Jack Roush was ecstatic after the strong start by the teammates in the title battle.

"A lot of cars fell out and I think it's a heartbreak day for a lot of teams, but we were lucky," Roush said. "That was great that they had plenty of gas today and we didn't have any problems."

With qualifying rained out on Friday and the lineup set by owner points, all the drivers in the championship battle started up front and seven of them finished among the top 13.

Earnhardt, who needed a relief driver here in July after being burned in a sports-car crash the previous week, ran strong all the way Sunday, finishing third. If the championship was determined after Sunday, Earnhardt would win the tiebreaker based on his four wins this season.

He was followed by rookie Kasey Kahne, Jamie McMurray, Joe Nemechek, Jeff Gordon, Elliott Sadler, Michael Waltrip, Kevin Harvick, Jimmie Johnson, Sterling Marlin and Mark Martin.

Gordon, Sadler, Johnson and Martin are all among the title contenders, with Gordon, who began the day with a five-point lead over teammate Johnson, now third, nine points behind the leaders and one point ahead of Kenseth. Johnson fell to fifth, 30 points back.

Three of the contenders ran into big trouble Sunday.

The action got started early when Greg Biffle spun former New Hampshire winner Robby Gordon into the wall, bringing out the first caution of the day on Lap 17.

On Lap 64, Robby Gordon ignited a multicar crash, drawing a two-lap penalty from NASCAR after hitting Biffle from behind. Tony Stewart tried to go around Biffle and Jeremy Mayfield and all of them wound up damaged.

Mayfield, who drove his way into the title chase with a victory at Richmond, and 2002 series champion Stewart got the worst of it. Both had to spend considerable time in the garage for repairs and wound up dropping out of the race early, with Stewart finishing 39th and Mayfield 35th.

An engine failure knocked Ryan Newman out late after he had briefly worked his way into the lead.

The day began with the top 10 separated by a total of just 45 points. Sunday's problems left the trio far behind Busch and Earnhardt, with Stewart 124 points back, Newman 136 out and Mayfield 142 behind.

"To try to make up that amount of points in nine more races is virtually impossible," Stewart said. "I can promise you one thing, though. This team has never given up and they're not going to give up now."
