The frame rate deteroriates the longer a game goes on, usually, presumably due to more units, deformed terrain, etc. I feel like some maps are worse than others (Rzhev being the worst offender in 2v2 at least, not sure why). Also, player count understandably plays a role; 1v1 is a lot less taxing than 4v4.
If it just suddenly drops in an instant, then I don't know. To me it usually starts out with 80-ish FPS and then drops to 40-25 depending on map, game length and player count.
