Exexute once per life!

Hello, i'm currently making a SimpleVIP Plugin, and i want the statement to give player Armor Kit once per life so he would get new armor after death!
So this is my code that i want to execute:

PHP:

 $e->getPlayer()->getInventory()->setHelmet(Item::get($this->getConfig()->get("Helmet")));
$e->getPlayer()->getInventory()->setChestplate(Item::get($this->getConfig()->get("Chestplate")));
  $e->getPlayer()->getInventory()->setLeggings(Item::get($this->getConfig()->get("Leggings")));
                                                             $e->getPlayer()->getInventory()->setBoots(Item::get($this->getConfig()->get("Boots"))); 
                $p->sendMessage("[SVIP] You recieved your kit!");
            }else{
                $this->getLogger()->info("[SVIP] Kit was'nt given to the VIP player, something went wrong"); 


Execute it on PlayerRespawnEvent and you could also put it in there inventory when they join again if you wanted fresh gear all the time.
