WDS500 Black SSD Fail

I have had this drive in my system for over a year, it is the boot drive. Noticed recently that the system is going down after a few hours with the message “cant find any boot device”. Only by power cycling can I boot my system again. The WD SSD dashboard shows everything is ok. I managed to contact support (Luis Pedro) who asked me to send in a report .zip file. This I did but haven’t heard a thing since.
