C# XNA Draw Multiple Sprites at Random Position

I am creating a game in XNA and wish to have multiple sprites drawn at random positions. The problem I have is that the sprites appear to redraw at a new position each time the Draw() function is called. This is making them flash around the screen randomly. I want them to draw once and stay in that position.

I have created a List to hold the sprites:

List<Texture2D> kiwis = new List<Texture2D>();

Then in the LoadContent() function I have added sprites to the list:

 kiwi = Content.Load<Texture2D>("Sprites/kiwi");
 if (kiwis.Count() < 4)
 {
      kiwis.Add(kiwi);
 }

Then in Draw(), I have:

foreach (Texture2D kiwi in kiwis)
{
    spriteBatch.Draw(kiwi, kiwiPosition, Color.White);                                          
}

This is the kiwiPosition Vector2:

 kiwiPosition = new Vector2(random.Next(30, 610), random.Next(30, 450));

Thanks in advance :)

In addition to my comment, insert and replace with the following as required

public class Fruit
{
     private Vector2 pos;
     public Vector2 Position
     {
         get{return pos;}
         set{pos = value;}
     }
     public Texture2D Texture {get;set;}

     public Fruit(Texture2D tex, Vector2 pos)
     {
         Position = pos;
         Texture = tex;
     }
}
List<Fruit> kiwis = new List<Fruit>();

kiwi = Content.Load<Texture2D>("Sprites/kiwi");
if (kiwis.Count() < 4)
{
    kiwis.Add(new Kiwi(kiwiTex, 
                       new Vector2(random.Next(30, 610), random.Next(30, 450)));
}

foreach (Fruit kiwi in kiwis)
{
    spriteBatch.Draw(kiwi.Texture, kiwi.Position, Color.White);  
}

The difference between this approach and your current approach, is that your position will only get set once instead of once per frame
