Why is my camera shutting down and screen turning on and off

My Canon M50 has been turning off all together. I fully charge all my batteries and the SD cards I have I’ve used with the camera before. It will record up to about 15 minutes and then shut off and the video doesn’t save. I had to record the first half of my video 3 times because the first time I thought it was just the battery. My camera is set to record up to 30 minutes now that time is cut in half. Also the screen keeps blinking on and off, making it impossible to use as a touch screen. And all together. I think my camera just might be broken? But if anyone could help I would appreciate it.
