why my data store have a chance to reset data?

hi for the past few months i've been using this script for stats data store. but sometimes your data will be resetted. is there a way i could fix it?

local DataStore = game:GetService("DataStoreService")

local myDataStore = DataStore:GetDataStore("EpicStorage")

	game.Players.PlayerAdded:Connect(function(player)
		local leaderstats = Instance.new("Folder")
		leaderstats.Name = "leaderstats"
		leaderstats.Parent = player
			
		local minutes = Instance.new("IntValue")
		minutes.Name = "Minutes"
		minutes.Parent = leaderstats
		
		local data
		local success, errormessage = pcall(function()
			data = myDataStore:GetAsync(player.UserId.."-minutes")
	end)
	
	if success then
		minutes.Value = data
	else
		print("Error when saving data")
		warn(errormessage)
	end
end)
	
game.Players.PlayerRemoving:Connect(function(player)
	
	local success, errormessage = pcall(function()
		myDataStore:SetAsync(player.UserId.."-minutes",player.leaderstats.Minutes.Value)
	end)
	
	if success then
		print("Data successfully saved!")
	else
		print("Data save is unsuccessful!")
		warn(errormessage)
	end
end)
