Laser disconnecting randomly during a job

I love my D1Pro 20W and have never had any issues with it…until recently. I was able to process whatever I wanted. Back in February I hurt my back, had spinal fusion surgery in April and have not been able to get upstairs to work on anything until this week. I came back upstairs this week to pick up where I left off. I guess the joke was on me. I performed all of my updates and was ready to go. When I go to process even the littlest thing it is disconnecting at various times during the job. I have tried just engraving shapes and single letters and cutting shapes and letters. No matter what I do it seems to disconnect at some point, sometimes it will stop halfway and others it will go for about a second. After reading various posts I have disabled the USB selective suspend, replaced the cord from my D1 to my laptop, cleaned all of my lenses and anything else I saw the briefest mention of and I am still having the same issue. Does anyone know of any other fixes or suggestions for me?
