Weird. Never hurts to try a Reset. Hold together Home and Power buttons for about 15 seconds, let iPhone turn off itself and then it will turn back on.

It may be a heat related issue - check for loose connections. Does the battery look swollen? It may be expanding a little when hot?

If not then you may need to replace the display
