using coroutines

I know a little about programing but these are new to me following the 3d buzz vids on making a 2d shooter. Anyway everthing works fine until I add Startcoroutine(Destroyship()) when I save and play the code works once every now and then it will work twice and then I get know collision what so ever. here is the scripts in using c#

 // check to see if enemy collides with the player
    void OnTriggerEnter(Collider otherObject)
    {
        if (otherObject.tag == "enemy")
        {   
            
            player.Lives--;
            Enemy enemy = (Enemy)otherObject.gameObject.GetComponent("Enemy");
            enemy.setpositionandspeed();
			
			StartCoroutine(Destroyship());            
          }   
    }
    
    //get ship to explode and reappear 
    IEnumerator Destroyship()
	
    {
        Instantiate(explosionprefab, transform.position, Quaternion.identity);
        gameObject.renderer.enabled = false;
       transform.position = new Vector3 ( 0f, transform.position.y, transform.position.x);
        yield return new WaitForSeconds(1.5f);
        gameObject.renderer.enabled = true;

    }
}

So know one has any Idea? All im trying to do is when my player is killed make him disappear for a second and then reappear at 0 on the x postion. It will work once if I go along time without dying it works twice. then all collision stops seems like it just keeps calling the coroutine and never goes back to the start function. I am at a loss!

There’s an error in this line:

   transform.position = new Vector3 ( 0f, transform.position.y, transform.position.x);

You’re setting the z coordinate to transform.position.x. Could this be causing the problem? The player will reborn in x = 0, but at some weird z coordinate.
If this isn’t the cause, add a debugging instruction like print(“I’m dead”) inside DestroySpaceship, so you can learn if the coroutine is effectively being called.
