Why Does Simulink Model Sometimes Pause Unexpectedly?

I have a Simulink model that very occasionally decides to pause on its own. As far as I know, I don't have anything in the model or settings that should make it pause. Almost all of the time it runs to completion. But every now and then I run it and it decides to pause, usually once, sometimes twice. When it pauses, different runs pause at different times. Not a problem if I'm sitting at my computer because I can just hit the play button to continue. But if I had to leave while it was running, it would be annoying to come back and see the simulation paused. Any idea how or why this happens?

Hi Paul,
One of the probable reasons might be due to breakpoints. Please check if there are any breakpoints in your system and disable them. Check the following link for breakpoints:
Hope this helps!

I thought breakpoints only apply when running the debugger (except breakoints in Matlab Function block),
I'm not running the debugger, just normal mode and hitting the play button. Can breakpoints come into play in this situation?
Regardless, I don't have any breakpoints set that I know of, but I'll check into this the next time the problem pops up.
