Definitely.  It takes a while, but even behind window glass (which is 
barely transparent to short wavelength UV) EPROMs can eventually lose 
their content.  It happened to a friend who had a machine with no top 
cover, on a desk under a window, after about 5 years.  But in direct 
sunlight, certainly just hours, and possibly just several tens of 
minutes if you're unlucky.
