2001 at Spa Montoya was on pole with Ralf Schumacher qualifying second.
Montoya had his engine blow on the second lap, de la Rosa had a big accident on the same lap. F1.com says : "Race stopped after four laps because of accident." I can't remember why they didn't stop it earlier. Anyway they had a restart, Ralf Schumacher's car was still did not have it's wheels on in time for the restart so Michael Schumacher started from pole the second time around.
