Exact same thing happened to me a year ago. It took multiple attempts by dealer to finally figure out the cause of problem. First they replaced battery. Next they replaced LPFP. Next they replaced HPFP. Car kept dying at random times which was dangerous and beyond frustrating.
Turned out solution was to replace fuel pump control unit (EKPS). Once this work was done problem disappeared. No recurrence for over a year.
This issue is very hard to diagnose because it only happens when engine is hot. Dealer had to let car idle for a long while and observed that EKPS was too hot. I’d have dealer check to see if this is the problem for your car. Good luck OP.
