Smok Mag P3 Won’t Turn On or Misfires

Hey everyone. I've been vaping for over a decade and this is just annoying as hell. I've had this mod for about six months and it will fire on it's own for 10s which causes it to shut down….OR…..sometimes it just won't even turn on. I've got batteries….a duel charger…I clean it…blah blah…any ideas of how to fix this issue would be welcome!
