Samsung Galaxy S4 restarts on its own and then turns off my mobile usage.

I came home last night after my phone had die, charged and turned it on to see that my phone wasn't connecting to a cell tower (I'm on Verizon by the way). I could still connect to a WiFi but I had no mobile data or even calling or texting features available. Now every few hours the phone restarts itself like this. Sometimes when I restart the phone my mobile data will work but then like 5 minutes later it will restart on its own and turn off mobile data again. I would very much like it if someone could help me fix both problems, thanks!
