Fox Sports announcer Chris Myers apologized to fans and drivers several times for the delay and problems.
In a statement, Fox said it had suspended use of the overhead camera indefinitely. It said drive rope that moves the camera back and forth failed and it had no immediate reason why.
"A full investigation is planned," the statement said.
Kyle Busch might want to look into why he can't seem to win a Sprint Cup race in Charlotte.
He entered a favorite after winning the Truck Series event last week and powering to a Nationwide victory Saturday. He was in the lead, though, when the nylon guide rope snapped and ran smack over it. Busch heard a "thunk" and knew he had problems. "It did have an effect of slowing my car down and I could feel it like, 'Whoa,'" he said. "That's weird and I don't know that anybody has ever seen that."
Busch's team got the car back in winning shape and he continued near the front. However, his race ended for good on lap 257 when his engine failed.
"Catastrophic engine failure. Seems to be that time of year," said Busch, who has yet to win a Sprint Cup event at the track he calls his favorite.
Busch did praise NASCAR for halting the race and allowing teams to repair damage, which he said was unrelated to his engine problems.
About the same time Busch's engine failed, Earnhardt's race concluded with a similar problem. Earnhardt had smoke and oil pouring out on lap 257. Greg Biffle slipped into the wall, sending him to the garage, and Dave Blaney and Travis Kvapil collided.
"We didn't have a really good car," Earnhardt said. "We know why. We can go back and feel like we can rebound from this real quick."
That started of series of incidents that ended things for some of NASCAR's most popular and successful drivers.
Defending series champion Brad Keselowski and Danica Patrick saw their chances end on lap 319 when they collided on a restart. It appeared that Patrick's boyfriend, Ricky Stenhouse Jr., forced her car up the track and she clipped Keselowski, who began his day in the Penske pits at the Indianapolis 500.
Keselowski took the blame for the wreck and apologized to Patrick, in her second Coca-Cola 600.
On the following restart, Mark Martin clipped Aric Almirola and set off a six-car wreck that caught up four-time Sprint Cup champion Jeff Gordon and Stenhouse.
Kurt Busch, leading at the time, suddenly lost power and needed a wrecker to push him along into the pits to change the battery. He returned to the track in 15th.
And the problems weren't over, either. Truex Jr. brushed series points leader Jimmie Johnson on the next restart to send the five-time champion skidding sideways and collected Matt Kenseth, who leads the series with three victories this year and led 112 laps at Charlotte.
Johnson remained the points leader while Harvick improved from 10th to seventh with his second victory this season.
NASCAR, as usual, did its best to honor the military and those who've served their country on Memorial Day weekend. Busloads of troops were brought to the track and retired Lt. Col. Oliver North gave a pre-race speech. There were massive American flags, several flyovers and even an eagle named Challenger who swept down from the top of the race track.
