The heart muscle itself only receives oxygen during diastole(relaxation), but as heart rate increases the relative length of diastole shortens compared to systole(heart contraction). TLDR; your heart gets tired because it only gets oxygen while relaxed, and the relative amount of time spent relaxing is less.
