GPS works but only if usb connected first

Hey guys so I got a small issue going on. Its a big inconvenience more than anything. If I connect the battery first my gps powers up but never gets a lock. And this only happens if I leave dont fly the thing for a few hours.

I can start everything up by connecting usb and then plug in battery then disconnect usb and start up my telemetry radio.. After that if I unplug battery and then plug it back in the gps will get a lock and I get GDPS lock. Any Ideas on what causes this?

Ive done a few searches and come up with similar problems but nothing that is totally my issue, regardless I have tried some of the troubleshooting for the other issue but they did not help.
