Printer Stops in the middle of the print

My P1S has been working flawlessly for months and suddenly today it started stopping mid print. What happens is: it starts the print normally, then after an hour or so it just stopped mid-print, and its screen showed “ready to print” instead of the usual “printing x file” message. The screen controls were completely unresponsive, so I couldn’t manually pause or stop the print. After a minute or so, the printer just resumed printing on its own, but it had created a blob where it had stopped.

I thought it could be a glitch but after 10-15 minutes it happened again, on a different side of the print.

I see some people refer to the sd card as the culprit but if I remove the sd card the printer doesn’t let me send a print over wi-fi? It says insert an sd card, so not sure what else to do?

Has there been any formal response on this?
