Webber. On lap 31, he moved past Webber, and into tenth place, behind David Coulthard. One lap later, the McLarens swapped positions, as Räikkönen moved into ninth. However, Räikkönen had to make yet another pit stop at the end of lap thirty four due to an electronics problem on his car. The stop lasted fifteen seconds and he rejoined last. Montoya made his first pit stop at the end of lap 35, rejoining in sixth. Michael Schumacher now led the race by thirteen seconds from Rubens Barrichello, and continued to pull away. Jarno Trulli, now in third place, drove sharply over the kerb at turn eight and lost a piece of his car on lap 38. Nick Heidfeld pitted at the end of lap 38 and rejoined the race in eleventh. Takuma Sato, meanwhile, had caught Olivier Panis's Toyota, and overtook him on lap 40 for fourth place. Schumacher pitted at the end of lap 42 with a fifteen-second gap to his teammate, and Barrichello assumed the lead. Schumacher's 10.3-second stop fuelled him to get to the end of the race. Barrichello then pushed hard, attempting to leapfrog Schumacher. Heidfeld retired on lap 45, and Sato pitted on the same lap for his second and final pit stop. Sato rejoined in sixth place, behind Montoya. Jarno Trulli pitted on lap 46 and rejoined in fifth place, behind Olivier Panis, although that quickly changed when Panis pitted at the end of lap 47. Panis rejoined behind Sato, and Coulthard pitted on the same lap for McLaren, rejoining in ninth. Fisichella, on Bridgestone tires, then suffered a left rear puncture on lap 49. He took the opportunity to make his final fuel stop, rejoining near the back of the field. Barrichello had been pushing hard, and so when he finally stopped for fuel on lap 51, the gap between the two Ferraris had been cut to approximately two seconds - Barrichello had cut the gap by approximately thirteen seconds. On lap 52, Barrichello went up the inside of Schumacher in turn four, but Schumacher cut across the front of his teammate. The two cars nearly collided, and Barrichello then, contrary to Todt's earlier statements, was told to remain behind Schumacher. The battle between the two Ferraris meant that Montoya and Trulli were catching them. Sato was, in turn, catching Trulli for fourth place. David Coulthard pitted on lap 55, and, similarly to
