Respawning a player after a certain amount of time

Hey guys,

I am working on a third person game where if my character falls in water, I want them to die and respawn at a respawn point. My current code isn't working... does anyone know how to achieve what I'm going for?

 public Renderer rend;
     public Transform respawnPoint;
     public GameObject Player;
 
     void OnTriggerEnter(Collision collision)
     {
         if( collision.gameObject.tag == "Player" )
         {
             rend.enabled = false;
             StartCoroutine (RespawnDelay ());
             Player.transform.position = respawnPoint.transform.position;
             rend.enabled = true;
         }
     }
 
     IEnumerator RespawnDelay ()
     {
         Debug.Log ("dead");
         yield return new WaitForSeconds (5);
         Debug.Log ("respawn");
     }
 
     // Use this for initialization
     void Start () {
         rend = Player.GetComponent<Renderer>();
