The defeat sees Stanley five points off the play-offs and has given them a tough task of keeping up with the top seven.
Coleman said: "That wasn't my Accrington team out there. We didn't play anywhere near like we can. We were a million miles from where we usually are and Burton ran out worthy winners.
"We didn't pass, cross or defend like we can and we looked tired and jaded. I don't know where the next three points are going to come from."
