Harriers missed a chance to edge back closer to the top of the table as they were beaten at Aggborough 3-1 by Alfreton on a frustrating afternoon.
Against a flat back five and a firm defence, Harriers had to break Alfreton down to secure any openings but within the first dozen minutes or so they managed to do so with Joe Lolley who twice struck off target before midfielder Lee Fowler, back in the side, almost found the back of the net with a cross that looped dangerously towards goalkeeper Jon Worsnop's top corner.
And on 17 minutes Harriers did take the lead and from the visitors' point of view it was a poor piece of play that saw them robbed of the ball by Amari Morgan-Smith in a dangerous area; from there, though, it was superb stuff as the hit-man charged forward with menace before playing in Callum Gittings
who coolly finished, knocking the ball in off the post.
Former Harriers man Tom Shaw struck off target with a wayward effort after 26 minutes but, within 60 seconds of that Lolley almost put his team ahead up at the other end after another driving run but his rising shot curled narrowly wide of the upright.
In the final seconds of the half there was a chance for 2-0 as Lolley beat the offside trap and raced down on goal - he seated Worsnop but in trying to round him he ran the ball out of play and narrowly missed out on the chance to score.
Early in the second half Gittings nodded an effort wide for Harriers but on 53 minutes Alfreton levelled with their first real attack of the game and their first goal in more than 400 minutes as Michael Wylde rolled the ball home after a mix-up at the back saw it break free in the area.
There was almost an instant response from Harriers as AMS turned well on the edge of the area and tested Worsnop with a rising shot - the keeper turned it away for a corner and watched on as the ball came in, met by Gash and deflected on to the bar and away.
AMS then warmed the keeper's hands with a drive, low towards the near post and another as he came to meet a looping ball but, in between, Alfreton's Connor Franklin saw his header from a corner held well by Lewis on the line.
Aflreton did steal ahead, though, and it came on the back of some controversy as AMS was sent off for a second yellow card. He'd been clearly taken out by Dan Meadows but desperately scrambled to stay on his feet, in doing so eventually fell into Shaw - the referee seeing a foul and one worthy of that second booking.
Regardless, Harriers were then caught off guard as the play restarted and Wylde was free again to stab home as the ball fell to him to make it 2-1 before Akinde spurned a wonderful chance to make it 3-1 when he stabbed wide when one-on-one.
A fine team move from Harriers almost levelled things at 2-2 as Storer drilled one wide of the post before Gash, from a free-kick, then warmed Worsnop's hands with a rising shot of his own.
Harriers attempted to try and find a leveller but in the final moments the game was put beyond them; Lewis conceding a penalty for fouling Akinde in the area, the hit-man slotting home the spot kick to make it 3-1, secure what seemed at one stage as a wholly unlikely away victory, and condemn the hosts to rare back-to-back defeats.
