iPad Mini 6 Pink Screen Appears and Restarts IPad

I am in DESPERATE need of an answer for my IPad issue.

For a couple of days now, my IPad Mini 6 will randomly get a solid pink screen and restart over and over again. Afterwards goes back to a normal speed, but not long after again I get the solid pink screen and restart. I have let the IPad charge overnight, turned it off for days and left alone, restarted the IPad, deleted apps and it still persists. Sometimes after not touching the IPad for a couple of days it seems fine, but hours later it starts up again. I recently purchased this secondhand and it was fine for a couple of months. Please please help me!
