Lee McEvilly denied Burton a repeat of their FA Trophy victory with a late equaliser for Accrington at Eton Park.
Burton ran out 4-2 winners two weeks ago, but this time it was a much tighter affair with headed goals by Aaron Webster and McEvilly at either end of the second half.
Webster put Burton in front two minutes after the break but the Northern Ireland international McEvilly - currently on loan from Rochdale - struck in the 82 minute to leave Burton without a win in five Conference games.
In the first half, the biggest threat was posed by McEvilly's fellow striker Paul Mullin as Accrington had a slight edge.
In the 25th minute Mullin was on the end of a Lutel James cross but saw his header bounce away after hitting the far post, and in stoppage time the striker headed over from 8 yards from a Paul Howarth free kick.
Webster made the most of his headed chance as Burton made a bright start to the second half.
The full back, who had scored twice against the visitors in the Trophy clash, again proved a thorn in their side when he rose magnificently to head home Craig Dudley's corner.
As the game opened up, Burton had opportunities to make sure of their first league win of the year.
But Dale Anderson twice over ran the ball with the opposing defence in disarray, sub Andrew Corbett volleyed over from 10 yards and skipper Darren Stride was denied by the legs of goalkeeper Jon Kennedy.
Burton were made to pay for failing to press home their advantage when a break away attack by the visitors resulted in McEvilly arcing a 12 yard header over goalkeeper Matt Duke after a cross by sub Dean Calcutt.
