While recording my Sony Handycam HDR-SR5 just shuts down randomly with a fully charged battery! Sometimes it goes for a couple of minutes sometimes for half an hour. Supervised or not it randomly just turns completely off.
Has anyone heard of this issue and maybe suggest a route to fix it?!

I'm really new to using this equipment. I bought it as a display model from Best Buy which they conveinently have no clue how to help me.
