Sometimes when I go to play on my tablet, It won't turn on but after a while ir'll turn back om! Why is it doing this?

Could be overheating, battery connection is loose, bad battery. Nothing much you can do for a tablet unless you can open it up and check connections and make sure it's clean on the inside so nothing is blocking the vents or components.
