Lincoln missed out on a third straight Conference Premier victory after being held to a draw by strugglers Chester.
Delano Sam-Yorke fired the Imps into the lead by slotting from close range after a defensive mix-up.
But Chester levelled through Matty Taylor, who lashed past Nick Townsend.
Lincoln's Alan Power then saw his penalty saved by Aaron Chapman after Matt Brown handled in the area and the visitors almost won it at the death but Townsend parried to deny John Rooney.
Lincoln City manager Gary Simpson told BBC Radio Lincolnshire:
"We could have won it in the first half, but I said to my players at half-time that the only team which could have beaten us today were ourselves.
"We allowed them to get back into the game, they got the goal and then had a couple more opportunities, we then had the penalty and I don't know how we missed when Nat Brown shot over the bar late on as well.
"But it's another point, another game unbeaten and we just move on.
"We played some great stuff in the first half on a difficult pitch but [in the second half] they turned us round, got their wide players cutting in and we didn't close them down as well. We were at sixes and sevens late on, but we had some opportunities and could have or probably should have won it."
