Help with spawning Prefabs that go towards a player

Here's a spawner script:

 {
     public float spawnTime = 5f;
     //The amount of time between each spawn.
     public float spawnDelay = 3f;
     //The amount of time before spawning starts.
     public GameObject[] enemies;
     //Array of enemy prefabs.
     public Vector3 enposition;
     void Start ()
     {
         //Start calling the Spawn function repeatedly after a delay.
         InvokeRepeating("Spawn", spawnDelay, spawnTime);
     }
     void Spawn ()
     {
         //Instantiate a random enemy.
         int enemyIndex = Random.Range(0, enemies.Length);
         Instantiate(enemies[enemyIndex], enposition, transform.rotation);
     }

Here's a enemy move toward player script

 public Transform Player;
 public float speed = 2f;
 private float minDistance = 0.2f;
 private float range;
 void Update ()
 {
     Player = GameObject.FindWithTag ("Player").transform;
     range = Vector2.Distance(transform.position, Player.position);

     if (range > minDistance)
     {
         Debug.Log(range);
         Player = GameObject.FindWithTag ("Player").transform;
         transform.position = Vector2.MoveTowards(transform.position, Player.position, speed * Time.deltaTime);
     }
 }

What you do is attach the spawner script on an empty gameobject at the position you want the enemy to spawn and drag your prefab (with the enemy move toward player script on it) into the slot in the inspector on the spawner.

is there any way i get the enemy to spawn the all over the out side and come towards the Player. and When i ran your srcipt it only spawn the enemy once . Thanks @Zoogyburger
