JTech Pro stops during burn

Hello. Help needed.
I have been running my jtech pro laser on a Shapeoko 3xl via Lightburn for over a year with no issues. Today after 12 of my 15 burns it stopped working…. Reset unsuccessful so waited a few minutes and reset worked…. But after burning for 30 secs it switched of again.

If anyone can help and let me know if you need more info…. Thank you all
