MORECAMBE picked up another vital three points to keep their play off hopes alive.
Two late goals gave Sammy McIlroy's side a fine win after Lincoln had battled back into the game.
Morecambe had the lead at the break thanks to a goal from a long range effort by Craig Stanley.
The Morecambe midfielder scored with a 30 yard shot that took a wicked deflection off the head of Phil Jevons and flew past Rob Burch into the top left hand corner of the Lincoln goal.
Lincoln hit back on 66 minutes with Cian Hughton slotting home David Somma's right wing cross as the home side enjoyed a period on top.
But Morecambe battled on bravely and took the lead for the second time on 82 minutes when Paul Mullin's close-range header was adjudged to have crossed the line despite the best efforts of Burch.
Wayne Curtis capped off the afternoon with a fine individual goal two minutes into injury time as the Shrimps claimed another valuable three points.
