We see in the fight with Sheer Heart Attack that a Stand's range is a physical limitation insofar as how far that Stand can be from its user. So, just like Echoes was physically unable to move more than 50 meters from Koichi to continue tracking Kira, Star Platinum or any other close range Stand can't move beyond its range. We even see that happen when Josuke tries to use Crazy Diamond against Surface when he's stuck in place and he can't reach because he's just out of range.
