The top of the table clash ended advantage Shoreham as the visitors opened up a seven point gap.
It could have been so different as the Stones raced into a three nil lead, courtesy of Ike Bignell, Johnny Phillips and Tom Barton. Shoreham pulled two back before the break through Charlie Watts and Ryan Stevens.
Stevens completed his hattrick in the second 45 to send the three points back to Sussex.
The Stones have an opportunity to close the gap with two games in hand scheduled in the New Year.
