Default [Q] LG Mach - slow resets need data

Hello,
I have an LG Mach. Today it has started running really slow and now it will not even let me use it. When powered on about every 3 - 6 seconds it locks up then after it unlocks it has closed all programs and it is back at the home screen with no data or wifi connection. Just like it just turned on.

I have tried soft reset and safe mode but it still does the lock up.

I tried to get the photos and contacts from usb but the constant resetting turns off the usb also.

Can anyone thing of a way that I can get the photos and contacts off the device before a do a hard reset?

Thanks
