Hill and Prost had built up a large lead by lap 11 and continued to move ahead through the field during the pit stops. Hill even managed to extend his lead over Prost, whilst Schumacher was beginning to challenge Senna. Schumacher attempted an overtaking manoeuvre on Senna, but instead left the track, going over a sand trap. He lost fifteen seconds, but crucially not his race position. As Hill began to close in on Prost, after losing position, Prost's Williams began to handle oddly and on lap 41 Hill retired from the race due to engine failure.
