Extremely bright light grew faint and stopped

On August 25th I was outside looking at the stars in the clear spots between the clouds and also texting on my phone.  After sending a text I looked up and saw what appeared to be an extremely bright satellite heading north that I had not noticed before; which was past the halfway point of its trajectory by the time I saw it, if it was traveling horizon to horizon.  I watched it drift a few degrees in the sky and it started to get faint to a brightness of a regular satellite or a star and I thought it would continue to the horizon but it stopped.  I watched this light stay in place for approximately 2 minutes until it was covered by a large group of passing clouds.
