Your movie could be corrupted and ends after a certain amount of time. or your USBthumbdrive could be cutting out and stops streaming the video. Try placing a movie directly onto the Ps3 and make sure it isn't the movie file. If it is than you don't need a new USB, If it doesnt stop then its your USB, and you may need to purchase a new thumbdrive.
Hope this helps ^^. Please dont forget to rate, Thanks
