The American then couldn’t get his car restarted for the final five-minute burst, and despite Prema exhortations to turn it “all off and then on again” the reset didn’t work.
Sargeant was still fastest when the chequered flag fell, but Vesti and Trident driver David Beckmann were on quicker laps, and Vesti finally claimed pole by 0.123 seconds.
That was redemption for reigning Formula Regional European champion Vesti, who set a quicker time than Sargeant’s before the second stoppage, only to have that lap taken away for running too wide at Turn 9.
First-round winner and championship leader Oscar Piastri this time brought up the rear of the Prema trio, the 2019 Formula Renault Eurocup champion and Renault F1 Junior completing a 1-3-4 for the Italian team.
Reigning German Formula 4 title winner Theo Pourchaire made a big step forward from the opening weekend, the Frenchman setting a time good enough for fifth in his ART Grand Prix machine, while the second Trident car of free-practice pacesetter Lirim Zendeli will share the third row with him.
Briton Olli Caldwell made it three Trident cars in the top eight.
The Spanish-Venezuelan plummeted to ninth as others improved, and will share the fifth row with last weekend’s reversed-grid race winner, Red Bull junior Liam Lawson (MP Motorsport).
