Not sure if this applies to the topic but I spent about 10 years in the golf business as assistant professional. I have always loved the sport. But after about 8-9 years I realized that I was not really playing that much golf (maybe once every couple weeks). When I was done working, I didn't want to be at the golf course. What added to this new development was the fact that my girlfriend/wife was also a golfer and likes to play so she would always want to go out to the course and play when I was off (and I just didn't want to). So I figured I would find something else to do that paid very little and have more time off so maybe I would start "wanting" to play again. So, that's what I did. It's worked out great. Golf is now really my only hobby also (as stated above) so I enjoy it much more when I get to do it. I never really "quit" but I certainly didn't have the desire to play. Too much of a good thing?
I should add this in. When I was working in the business, I only had one day off a week. And when I did work, it was never an 8 hour day (usually 10-12 most of the time). Plus I worked almost all the major and minor holidays. That may have also had something to do with "golf burnout".
