Leaderstats script works only once on spawn, and doesnt work thereafter. Whats wrong?

This script will only work once after the player dies or gets a kill after they spawn in. Thereafter it will not work. Why is it only registering once??

local DataStore1 = DataStoreService:GetDataStore("DataStore1")
