DM-40 Not Powering on?

I recently got my xdj-rx2 and was excited to try it out, when I first set it up with my pair of DM-40's it worked flawlessly and I played around with it for about 30 minutes before I went and relaxed a little bit. Later on that night I tried using it again but for some reason I couldn't get the it to power on after some trouble shooting and googling nothing was working. But then randomly the unit turned it self on and I could start playing music through it again. 20 minutes or so later while I was playing the unit randomly powered off and I haven't been able to get it to work since then despite all of my trouble shooting efforts. No one else seems to be having this problem?
