"Somebody two cars ahead of me decided to stop in the go lane and why he did that I have absolutely no idea, but these cars don't stop very well on the wet asphalt," he said.
Harraka also blew a tire later in the race and finished 39th. "I don't know what to say except that stuff happens," he said.
"We have done a lot of work and there are a lot of people who have contributed a bunch as a group. Our whole Ford group has tried different parts and tested different things," Edwards said.
"We've leaned on Marcos Ambrose a lot and his expertise in road racing, and I think you saw that in qualifying and in the race with myself, Greg (Biffle) and Marcos all qualifying in the top four. That's a pretty big feat for us and to be running as well as we did."
"It's heartbreak for me and everybody on the team," he said. "You've got to defend them in the way that when they do the fuel calculations based on other runs, in the other runs you're stuck in traffic and can't run that hard.
"Then you get in clean air and they're asking me to run as hard as I can, and I'm doing that, you're going to use a little more fuel. It should have been a little smarter."
5 key moments
1 . Before the race started, the race had its share of drama. David Reutimann came to an abrupt stop on pit road as cars exited for pace laps and Alex Kennedy then stopped quickly behind him. Paulie Harraka then slammed into Kennedy's car.
2 . Martin Truex Jr. showed he had a fast car when he moved into the lead for the first time on Lap 41 once Brad Keselowski pit for fuel and tires. He led the next 21 laps.
3 . Tony Stewart slammed into the back of Denny Hamlin on Lap 68 doing damage to both drivers' cars and ending any shot at the win for either.
4. Truex took over the lead on Lap 83 from Jeff Gordon when he was one of 15 drivers to stay out on the track and not pit under caution.
5. Any chance Juan Pablo Montoya had to run down Truex for the win came to an abrupt halt when he ran out of fuel on the last lap.
