"Something's flapping on my front tyre," Hamilton tells his team.
Could have been a leaf.
Whatever it was it ain't there now.
A terminal problem for the Renault driver, who looked on course for a podium at one point in this race.
He retires, elevating Esteban Ocon's Force India into 10th place.
That's 129 races now without a podium for Hulkenberg - a new (unwanted) record.
A 1:45.656 gives Hamilton a new fastest lap of the race. Ricciardo just can't get near him.
A 28-point title lead looms for the Mercedes man.
Mercedes to Lewis Hamilton: We want to keep the field compressed. We don't want to give anyone a free stop if a safety car comes.
Hamilton: I don't get your tactic. It doesn't feel comfortable driving off pace.
Mercedes: If you are not comfortable, you can dictate the pace.
No dramas at Mercedes it would appear. Hamilton is matching and bettering Ricciardo's pace again and the gap is stabilised at around 2s.
Just 14 cars running, by the way.
Six retirements are Ericsson, Kvyat, Alonso, Vettel, Verstappen, Raikkonen.
Ricciardo just set a lap 2.6s faster than Hamilton...
Mistake by the Mercedes man?
Top 10: Hamilton, Ricciardo, Bottas, Sainz, Perez, Palmer, Vandoorne, Stroll, Grosjean, Hulkenberg.
Hamilton sets a new fastest lap of 1:47.133 and his lead to Ricciardo is out to 2.2s.

Lewis Hamilton is absolutely on it. This is a spectacular restart to the race.
Race control confirms we are now into a "timed race situation".
22 mins to go...
Magnussen out-brakes himself into Turn Seven. He's running 13th.
Hulkenberg is 10th after that hydraulic issue. Team-mate Palmer running sixth.
Hamilton straight out into a two second lead over Ricciardo.
There really is no-one better in F1 when it comes to restarts.

Textbook from Hamilton throughout this race but now the gloves are off. Hamilton has much more to lose than Ricciardo so expect Ricciardo to really lean on him but does he have the pace?
We are about to find out.

Verstappen and Raikkonen have been speaking to the media. Raikkonen said "I don't know, there is always different views and I could not do anything to avoid it".
To recap, Vettel earlier said "not ideal is it, I don't really know what happened".
Hamilton and Ricciardo weaving down the straight to get heat back into those tyres.
