Disabling Shake Script After Certain Amount of time?

So basically, I'm trying to disable a shake script after 3 seconds for an Order 66. The ShakeScript is a while true function, and I'm trying to get it to end after 3 seconds.

	local players = game.Players:GetPlayers()
		for i=1, #players do
		local character = players[i].Character
		local shakescript = character:FindFirstChild("ShakeScript")
			if shakescript ~= nil then
				shakescript.Disabled = false
		end
	end


	game.Workspace.ShakeScriptAdder.ShakeScript.Disabled=false
	wait(3)
	game.Workspace.ShakescriptAdder.ShakeScript.Disabled = true

	local players = game.Players:GetPlayers()
		for i=1, #players do
		local character = players[i].Character
		local shakescript = character:FindFirstChild("ShakeScript")
			if shakescript ~= nil then
				shakescript.Disabled = true
		end
	end

This is the Shake Script if you need it.

while true do
local cam = workspace.CurrentCamera
cam.CFrame=cam.CFrame*CFrame.Angles(math.random(-3,3)/360,math.random(-3,3)/360,math.random(-3,3)/360)
cam.FieldOfView=math.random(69,71)
wait()
end

(There is another script that just distributes the ShakeScripts into each player. It works, it just wont stop.)

To start off, I would use a Remote Event and I suggest reading more about them and Remote Functions on the ROBLOX developer wiki as they are very useful since all games need to be filtering enabled. Also, I suggest not directly disabling the script itself, just disabling/enabling all the things you want the script to do.

This is what you would write for the client(local script):

local RepStorage = game:GetService("ReplicatedStorage")
local shakerEvent = RepStorage:WaitForChild("shakeEvent")

local function shaker()
--write what you want the event to do (an example would be workspace.Part.Transparency = 0)
end

shakerEvent.OnClientEvent:connect(shaker)

This is what you would write in the server script:

local Players = game:GetService("Players")
local RepStorage = game:GetService("ReplicatedStorage")
local shakeRemote = Instance.new("RemoteEvent")
shakeRemote.Parent = RepStorage
shakeRemote.Name = "shakeEvent"

local function shakeShake()
-- depending on whether you want the event to fire for all players when fired or only for the player firing it, What you would write for the event to fire for all players is:
	shakeRemote:FireAllClients()
end

-- if you want the event to fire only on the player firing it, you would write:
local function shakeShake(player)
	shakeRemote:FireClient(player)

--once you want the event to fire, you would put it wherever you want it to fire in the server script as:
shakeShake()
