Players animation sometimes stop while sprinting

Help and Feedback Scripting Support
#1

hello,
recently i made a stamina and sprint update for my game and when i tested it with some of my friends, i saw them having the animation played when they where sprinting but after some time i couldn’t see their animation.
how could i fix it?

Is your animation looped?

If so, then you must be referring to the problem occasionally happening, right? And if so, can you show us your code?

#3 
local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local anim = Humanoid:LoadAnimation(script.Parent.Animation)
local Exterior = Player.PlayerGui:WaitForChild("Stamina").Frame
local bar = Exterior.Bar

local Equipped = false

local NormalWalkSpeed = 16
local NewWalkSpeed = 25

local power = 10

local sprinting = false

local Mouse = Player:GetMouse()

script.Parent.Equipped:Connect(function()
	Equipped = true
end)

script.Parent.Unequipped:Connect(function()
	Equipped = false
end)

Mouse.Button1Down:Connect(function()
	if Equipped == false then return end
	
	anim.Looped = true
	anim:Play()
	Humanoid.WalkSpeed = NewWalkSpeed
	sprinting = true
	while power > 0 and sprinting do
		power = power - .03
		bar:TweenSize(UDim2.new(1.077, 0, power / 10, 0), 'Out', 'Quint', .1, true)
		--Bar.BackgroundColor3 = Bar.BackgroundColor3:lerp(Color3.fromRGB(255, 42, 42), 0.001)
		wait()
		if power <= 0 then
			anim:Stop()
			Humanoid.WalkSpeed = NormalWalkSpeed
		end
	end
	
end)

Mouse.Button1Up:Connect(function()
	if Equipped == false then return end
	
	anim:Stop()
	Humanoid.WalkSpeed = NormalWalkSpeed
	sprinting = false
	while power < 10 and not sprinting do
		power = power + .03
		bar:TweenSize(UDim2.new(1.077, 0, power / 10, 0), 'Out', 'Quint', .1, true)
		--Bar.BackgroundColor3 = Bar.BackgroundColor3:lerp(Color3.fromRGB(255, 166, 11), 0.001)
		wait()
		if power <= 0 then
			Humanoid.WalkSpeed = NormalWalkSpeed
		end
	end
end)

this is the local script in the tool

beacuse its a football where u use the tools to shoot pass etc, so i implemented the system on a tool
