MacBook Pro display switches off during use and does not turn back on until force restart - has anyone experienced a similar issue?

My MacBook Pro 2012 (retina) has the issue that the display switches off after using it for a while. The computer still runs, the fans are still spinning, the keyboard lighting is on and if I press a key it plays a sound. However there is no way of turning the display back on except forcing a shutdown and restarting. Below is the error I was presented with the last time it happened.

I have recently wiped the computer and re-installed the latest macOS version, so I'm afraid its hardware related - would like to hear if anyone has come across this issue and has any ideas how to resolve it?
