Erik Jones won the Camping World Truck race at Phoenix International Raceway for the second year when a power outage Friday night forced NASCAR officials to end the event with 24 laps left.

The start also was delayed more than an hour because of an outage that knocked out the track's lights.

The 18-year-old Jones started from the pole en route to his third victory in 12 starts this year.

Last year at the mile oval, Jones became the series' youngest winner at 17 years, 4 months. Cole Custer broke the record in September at New Hampshire, winning at 16 years, 7 months, 28 days.

Jones gave Kyle Busch Motorsports its 13th victory in the first 21 races. Busch has seven victories in the No. 51 Toyota he shares with Jones, and Darrell Wallace Jr. has won three times in the No. 54 Toyota.

Points leader Matt Crafton was second in his bid for his second straight season title. He increased his lead over Ryan Blaney to 25 points heading into the season finale next week in Homestead, Florida.

Custer was third, followed by Blaney, Ben Rhodes and Wallace.
