Firestudio Project keeps shutting off

So I have never had a problem with this up until recently, but my firestudio project will randomly shutoff while I'm using it and then start back up. After it starts back up it then quickly shuts off again..it gets to the point to where I have to tu it off with the power switch in the back. After a few minutes I can tu it back on and it will last a couple more minutes before this process begins again. Any ideas on what might be wrong and how I can fix this?
