One monitor is plugged in via the DVI port and the other via HDMI.  I think Austin was right that heat may be the problem.  I put a small fan in the case so it blows directly on the video card.  Psensor show the card being around 20°C cooler with the fan than without.   Thanks Austin. and everyone else who responded.
