Faulty card/PSU? or what I don't know..
You could be right on the edge of your thermal limit, and it doesn't have to be hot. It has to do with voltage/ temps/ core speed these cards seem to have a limit and if you can't cool it down enough they error or shut down. The higher the core speed you want to run the greater your cooling has to be and the lower your thermal limit becomes.
I noticed this when overclocking my 480, at a higher core 850+ I would error when the GPU for into the 90C and after about 6 minutes, but at stock clocks 95C no errors.
