Why does a ring tone keep shutting of my phones?

[AC Question]

I have 3 lg g3 and all 3 of them shut down and restart when I set the MacGyver theme as my ringtone. Sometimes they shut off when I start to pick them up, other times they shut off if the ringing goes for a while. Sometimes I'm able to take the call as if nothing was wrong. this doesn't happen with other ring tones.
