The GP3 race at Spa-Francorchamps was red-flagged after just 15 minutes of its scheduled 25-minute duration due to a heavy crash that befell Robert Cregan at Pouhon on lap four.
Daniel Abt was declared the winner, after he pulled off an opportunistic move on leaders Mitch Evans and Antonio Felix da Costa at Les Combes on the third lap.
As they were so intent with their own battle, they slid wide and allowed Abt to nip past the pair of them.
Matias Laine took the lead at the start from second on the grid, but ran wide at Les Combes on the opening lap and almost took out Abt.
Evans led, before da Costa dragged past him with a neat move into Les Combes on lap two.
But as he attempted to fend off Evans's attack a lap later, Abt jumped them both.
Abt clung on to his lead at Les Combes a lap later, forcing da Costa over the sleeping policemen on the inside of the corner as they raced side-by-side.
The race was soon neutralised as Cregan came off worst from a clash between himself, David Fumanelli and Alex Brundle on the run to Pouhon, in which Cregan was fired backwards into the tyre wall on three wheels.
The tyre wall appeared to trap him in the car, and with little chance of the race restarting it was red-flagged and called as a result.
Abt won the four-lap event by 0.3 seconds from da Costa and Evans. Tio Ellinas was fourth ahead of Laine.
Aaro Vainio saw his receding championship chances diminish even further, as he finished sixth, followed by Conor Daly and Lewis Williamson.
