Tim Wilkinson and Esteban Toledo, who were both tied with Gove after Friday's second round, each shot rounds of 2-under 70 and are part of a group in second place. Jamie Broce (67) and Kris Cox (69) joined Wilkinson and Toledo at 12-under-par 204.
Bill Haas shot a 6-under 66 and is tied for sixth place with first-round co-leader David Morland IV, who carded a 4-under 68 on Saturday. The duo is knotted at minus-10.
Gove began the round tied for the lead at 10 under par, but quickly got to 12- under par with a pair of birdies at the second and third holes. He gave one back with a bogey at the par-5 fifth, but made the turn at 12 under thanks to a birdie at No. 9.
Gove's biggest shot of the round came at the par-4 11th. The wind changed and his approach landed in a back, greenside bunker. Gove left his third shot in the trap, but chipped in from the bunker for the unlikely par.
'I just battled through those tough holes, 11 through 14, then you just have to go for it,' said Gove, who finished second to Toledo at this year's Lake Erie Charity Classic at Peek 'n Peak Resort.
Gove went for it alright. He collected birdies at 15, 17 and 18 to break out of the logjam at minus-12 and give him a piece of his second 54-hole lead of the season. He shared the 54-hole lead at the New Zealand PGA Championship before sharing 13th place.
'I remember getting off to a good start and then hitting one funny shot on No. 8,' said Gove, referring to his final round in New Zealand. 'Hopefully, I can learn from it and be patient tomorrow.'
Gove is a two-time winner on the Nationwide Tour, but has not visited the winner's circle since 1999.
Jeff Freeman shot a 5-under 67 on Saturday and is alone in eighth place at minus-9.
Tom Scherrer (66), Jeremy Anderson (71), Charley Hoffman (71), Jon Mills (73) and last week's Boise Open winner Greg Chalmers (68) are tied for ninth place at 8-under-par 208.
Defending champion Jeff Quinney made a move up the leaderboard on Saturday with a 5-under 67. He is part of a group tied for 22nd place at 5-under- par 211.
