Movieclip stop drawing bitmapdata continuously

[onenonly]

// currentTime
var currentPlayerTime = 0;

// Blank MovieClip
var timeLineEdit:MovieClip = new MovieClip();
	MovieClip(root).addChild(timeLineEdit);

// 60 seconds 
var movieDuration:Number = 60.5;

	// Looping through
	for(var j = 0; j<Math.ceil(movieDuration); j++){
		// instance of timeline MC
		var timeLineMC:timeLineClass = new timeLineClass();
			timeLineMC.timeLineX.text = j+1;

		// create bitmapData of timelien MC
		var timeLineBMD:BitmapData = new BitmapData(timeLineMC.width, timeLineMC.height);
			timeLineBMD.draw(timeLineMC);
			
		//make MC width of movie in seconds
		timeLineEdit.graphics.beginBitmapFill(timeLineBMD);
		timeLineEdit.graphics.drawRect(j*timeLineMC.width, 0, timeLineMC.width, timeLineMC.height);
		timeLineEdit.graphics.endFill();

	}
	
	
stage.addEventListener(Event.ENTER_FRAME, EnterFrame);
function EnterFrame(e:Event):void{
	
	// simulating player
	currentPlayerTime = currentPlayerTime + (1/30);
	
	// Moving timeline base on currentPlayerTime
	timeLineEdit.x = -((timeLineEdit.width/movieDuration)*currentPlayerTime);
}

I would appreciate any help at all.

Basically, I have a 800px width image thats represent one second in the movie.
Ex. 60.5 seconds of a movie should have a timeline 48,400px (timeLineEdit)
but, for some reason at the 42 seconds mark or 33,600px mark the timeline stop moving...

Extra Info:
The timeLineClass is a MC which is a timeline with a dynamic text that correlate to the seconds of the movie
