Seems like a vacuum leek or something

Fuel filter error will not show over scanner.
Under the rear seat is fuel tank. The fuel pump in the tank contains a filter sack. If that filter sack is full of debris (aka tank rust) the fuel pressure will drop and engine will stall die due to fuel starvation.

Physical inspection is necessary. clean the fuel filter or change to new oem part if it is shredded.

Have you tested your cars alternator?

Brother i have completely swapped my fuel filter and fuel pump with 2019 grandee. The whole rack. But still the same problem.

Plug in scanner when issue happens. Look for live sensor values, fuel trims specifically. U ll have a lead from there.
