Yes espresso shots do eventually die but they can be revived with a few simple steps.

What Causes an Espresso Shot to Die?
An espresso shot can die for a variety of reasons the most common of which are stale ingredients improper tamping over-extraction or temperature fluctuation.
Stale ingredients are the result of using espresso beans or grinds that are aged and will lack the flavor aroma and crema of a freshly brewed shot.
Incorrect tamping which is the process of packing the espresso grounds into the portafilter can lead to uneven extraction and unsatisfactory results.
Over-extraction which is when the espresso is left to brew for too long can lead to a bitter and unpleasant tasting shot.
Finally temperature fluctuation which is a common issue in some commercial espresso machines can cause espresso shots to come out too hot or too cold and will lead to a poor cup of coffee.
