Like all cells, stem cells undergo apoptosis when they are detected to be dysfunctional or aberrant. These situations arise when mutation or genetic damage causes them to lose vital features that normally signal other cells (as well as organelles within itself) that everything is ok -- when these signals are lost, the cell is programmed to die, either from within, or from other lymphocytic/monocytic cells that instruct them to die.
The other reason cells undergo apoptosis is senescence, but this does not really apply to stem cells.
