Iphone Randomly Restarting Itself to Black Screen?

[Infiniti7]

Anyone experience this? the screen goes black for about 5-10 seconds then the apple sign shows up on the black screen and it brings you to the home screen "slide to unlock"? i know i started a thread about this earlier but dont know how many people have looked at it sorry.
