I went through this last year.  Lots of coral losses, no time to really put into the tank, frustrated and kinda lost interest.  But i invested a ton of money into a new set up so i was also irritated I'd lose too much selling it off.   
 
So I've taken it easy, kept up water changes added a few coral here and there but nothing hi priced and just let the tank do its thing.  Tank has been set up 2 years now and no where near what others are in the same amount of time, but I've found a groove that works for me and lately things are turning around. 
 
I haven't had a signifant crash, or major algae issue in a long time, but I have struggled.  Talk to people here, find someone who can come over and help diagnose solutions for you.  Sometimes someone else will see something you are missing.  Don't quit.
