It seems like I can only use
Run out of time.
But how to describe there is no more something that is countable?
"Run out of time" and "have no time left" would get the same point across, but you're not counting a unit.
An example of this would be "you have five minutes left", but when time runs out you wouldn't usually say "you have no minutes left"
For another example we can use biscuits:
I hope this helps clarify the usage for you!
