My ipad turns off by itself

Does it turn off, or simply enter sleep mode? If so, you can change when it sleeps by choosing Settings -> Auto-Lock -> and select a time. Hope this helps.

Turn off you iPad by pressing both the ON/OFF button and the Home button at the same time unitl the little time marker goes off, wait 30 seconds and press the ON/OFF button and the Home button at the same time again until the Apple Logo appears in the center of the screen. It may take a minute of two waiting time before you see your desktop display again....this should correct most cases of the iPad shutting down by itself.

People telling to take back to apple!! Why the heck would people ask for help if try can do that????

Go to settings general then auto lock then you can switch it to what time you want it to shut off

Maybe some app is causing it to do that. Delete some unnecessary apps?

My battery says 100% and when I unplug from ac adapter it last 1 minute and shuts off. It then shows a picture of the battery with no charge (red line at very bottom of battery) Any help is appreciated.
