Radio Freezing topic

I have a Verizon Galaxy S4, SCH-I545 running stock, version I545VRUFNC5. The phone works fine for awhile, but then just freezes up. Mobile data stops transferring, the phone stops accepting calls. The odd part is that it will occasionally still make calls while it's locked up, but just won't receive. Restarting the phone fixes the issue for awhile, but it's incredibly annoying. Before I start throwing random roms on this phone, I was wondering if this is a known issue and if so how to fix it. I have tried searching, and while my forum-fu and google-fu are both indicating that others have had this issues, they are failing me when it comes to a solution.
