It's just the camera's way of making sure you are on an unexposed frame when you start to take photo's that matter. It should work fine after that.
That isn't correct; the camera sets 1/1000 shutter speed until you wind the film past 0. It will show 125 if you have the mode dial set to the 125 setting, or if you have manually set the shutter speed to 125 with the buttons.
I've heard people talk here about some sort of circuit board failure, maybe that is causing the fading away, but I don't know the symptoms of circuit board problems.
