why am I losing player.transform position in saved game when I change levels

I have a save/load script that works pretty well except when I change scenes. Example: scene1, I run around and hit "save" . Run around some more and hit "load" and I am back at where I hit the save button. In other words it works. now I run around and run into a trigger that sends me to the next level. So I'm at level 2, hit "load" and I DO go back to level1 where I saved, but I am NOT at the spot I saved. I am at the starting position of the level. I watch in the Inspector window as the var slot where I drag the player empties out. Anyone see what is wrong with the script? The commented out var Blur and MouseLook were to get unity to accept it and I don't think that is the problem as it DOES save position, just not when going to a different scene

 class ComponentsClass { 
     //var BlurEffect : Blur;
     //var Look : MouseLook;
 }
 var Components : ComponentsClass = new ComponentsClass ( ) ;
 var Restart: String;
 var playerPosition : Transform;
 var mainMenuSceneName : String;
 var Skin : GUISkin;
 var LoadPosition : String = "false";  //set to "true" is you want to load position or "false" to load only level
 private var LoadLevel : boolean = true;
 //private var Look1 : MouseLook;
 var pauseMenuFont : Font;
  private var PlayerX : float;
  private var PlayerY : float;
  private var PlayerZ : float;
 
 private var pauseEnabled = false;

     PlayerPrefs.SetString("LoadPosition",LoadPosition); //set loadPosition true or false

     Screen.showCursor = false;
     LoadPlayer();

             if(PlayerPrefs.GetString("LoadPosition") == "true"){   //save current position            
                 PlayerPrefs.SetFloat("PlayerX",PlayerX);
