Wycombe were forced to settle for a point at Edgar Street as Hereford United produced a stubborn defensive display to frustrate the promotion hopefuls.
After an entertaining first half which saw both sides create a number of openings, the Blues bossed the second period but couldn't break the deadlock as the hosts held firm.
Andy Sandell hit the post with a mishit volley and later headed a corner into the keeper's arms as Wanderers pushed in vain for the winner.
At the other end, Nikki Bull made a fine save in each half to deny Ryan Green and Stuart Fleetwood, but it is Wycombe who will feel more disappointed with the outcome.
Gary Waddock named the same starting XI for the third consecutive match, meaning 15-goal top scorer Scott Rendell continued in attack alongside Stuart Beavon.
Wanderers, looking to make it three wins on the bounce, were the first to threaten when Marvin McCoy fired over Adam Bartlett's bar from 20 yards after evading a couple of challenges.
The Blues continued to make the early in-roads, and Rendell glanced Scott Donnelly's free-kick just past the left-hand post before Kevin Betsy forced a save from Bartlett after latching onto the lively Stuart Beavon's lay-off.
Provider nearly goalscorer just before the 15-minute mark but, after being fed by Donnelly, Beavon sent a fizzing 20-yard effort whistling just the wrong side of the right-hand post.
A defiant Hereford grew in stature as the half went on and had chances of their own, firstly James McQuilkin curled an effort just over Nikki Bull's bar before the same man angled a low drive wide of the target.
And only a top save from Bull denied right-back Ryan Green finding the far corner and capping an impressive 10-minute spell for Jamie Pitman's Bulls.
But, just two minutes after almost falling behind, the Blues nearly broke the deadlock when Betsy's low cross from the left picked out Donnelly, who directed his close-range effort over the top.
As the half drew to a close, the game had a lovely ebb and flow to it with both sides playing at a high tempo and creating openings.
The start of the second period was equally lively and it was Wycombe who had the edge, seeing Gareth Ainsworth's powerful low cross cleared before Stuart Beavon volleyed over the top following an impeccable first touch.
Wanderers were gradually becoming more and more dominant but just lacked the killer touch, with one particular move seeing Kevin Betsy waltz past several defenders before Scott Rendell was denied inside the area.
At the other end, Nikki Bull produced a fine diving save to deny Stuart Fleetwood just moments after the Blues had brought on Andy Sandell and Jon-Paul Pittman in a bid to exploit a nervous-looking Hereford defence.
Within minutes of coming on, Sandell hit the woodwork with a mishit volley from 15 yards as Wycombe looked to turn the screw, before Bull denied Fleetwood's curling effort towards the bottom corner.
As the game approached stoppage time, Andy Sandell headed into Adam Bartlett's arms following a corner, but the breakthrough didn't come and leaves Wycombe three points clear of the play-offs.
