ssd randomly stopped working

my ssd randomly died.  Prior to this it would sometimes freeze.. and even not be recognized sometimes when i restart. but as far as I could tell it was just the sata cable coming loose.. I think when it heated it would expand and not get a good connection and it was more likely this would occur.  Usually wasnt much of an issue .. restarting usually worked.  However this weekend I came back after being gone for 2 days and the computer was on.. I was able to move the mouse but everything else was frozen so I restarted.   I havent been able to boot to that disk since.  

Luckily I just made a back up about a week ago.. but I still would like to try to get it working to get up to date data off it.  Any suggestions?
