V70 engine goes off

Hello together, 2 days ago my V70 T5 engine went out during the ride. I drove at 100km/h on the highway, when the engine started to jerk and within about 10s outside. After that the engine started, but went out directly again. After about 30min the engine ran again (very rough and no power) and I could drive to the next highway parking lot. Incidentally, a Volvo driver came by with a diagnostic device, but that could not be Verbi After about 30 minutes, the engine ran back to normal and I could drive home 20km without any problems. The engine was idle for about 15min and I disconnected the battery connection to clear the fault memory. Does anyone have any idea what that might be? I’ve had the car for 1-2 months and had no problems at all. I drove about 1000km with it. LG Karim
