iPad Crashes and then White bar at the top of screen

I have a weird problem with an iPad Air where it crashes after a little bit of use. I wasn’t able to figure out how much use it takes, but I got it to crash twice during a pass mark test. It crashes and shows the apple logo, then it starts to fade away and shows a white bar at the top of the screen. After you let it sit for a while, you can use it normally till it crashes again. I have attached some pics of the white bar.

Any ideas? Thanks
