I think it's a software issue. I am guessing that there is some "book keeping" function IOS is doing which renders the processor unavailable. From the time I notice that the screen is stuck until it gets unstuck is typically between one and three minutes. This appears to happen at random. I have turned off as many automatic features which require the CPU and this has reduced the frequency of screen freezing but not eliminated it.
