Lahiri, lying sole third on Saturday, admitted 'running out of gas' and ended with a rare over-par round of 71 and totalled 10-under 270 to finish tied-seventh.
Jeev, who needed a top-2 finish to secure his card for 2016, had a worse struggle with two-over 74 and finished at six-under 274 in tied 24th place after being tied-fourth overnight.
Among other Indians, Gaganjeet Bhullar had one bogey on the first and his only birdie came on seventh as his 70 got him a total of nine-under 271 and tied-13th place.
Rahil Gangjee had four birdies against three bogeys for a 71 that gave him a total of seven-under 273 and tied-18th place. More importantly, it saw him climb into Top-60 at 52nd place on Money List and gave him a chance to keep his card for 2016.

Asian Tour Order of Merit winner, Lahiri's fightback did not materialise and he felt he was let down by fatigue. He posted 71 and shared seventh place with Asian Tour honorary member Y.E. Yang, 2008 UBS Hong Kong Open winner, Lin Wen-tang of Chinese Taipei and England's Matt Ford.
He added, "Obviously I've got to manage my energy levels a little better now going to the next few weeks."
On his finish, he said, "Yeah, I'm obviously disappointed with how I finished, because there were a lot of World Ranking point the this week, and this gave a few away. But having said that, I'm pretty happy. If I can play poorly on a Sunday back nine and still finish in seventh position, then I'm obviously doing something right. Next week (CIMB Classic) is critical. That's probably the week that's going to decide to a large extent how the rest of the Order of Merit chase runs out and hopefully I can play well next week."
