Ipad Pro 9.7" is shutting off, restarting itself and having HEAVY lcd glitches

Ive had my Ipad for around two years now. I have never dropped it, never gotten liquid on it, and never gotten any debris in its holes. It has had one screen replacement but that was a year ago and there were no problems directly after it. Just recently my Ipad has began to go black screened and then restarting itself. The most concerning thing is whenever the screen will go completely 8bit and rainbow glitchy, like the LCD is broken, and then restart shortly after. Sometimes after one of these glitches it wont restart and I will have to do a force restart using the home and power button. After it restarts after both kinds of glitches it functions perfectly fine, but then it will glitch again anywhere from twenty minutes to three hours later. The attached image is not a picture I took, but its almost exactly like some of the glitches my ipad has done before shutting down. What should I do?
