Seems to be a fault with the idling system.

Get the throttle body and Automatic Idle Speed (AIS) cleaned and retest.

Are you able to restart easily after stalling?
Does holding the gas pedal slightly keep the engine running?

Have you tried retrieving for trouble codes?

With throttle opened resulting in stalling faster indicates a possible vacuum leakages between the MAF and throttle body or a fault with the MAF.

Check the air intake hose between the air cleaner and throttle body for vacuum leakages.

Not vacuum lines alone. Check if the air cleaner hose is cracked and is installed securely.

Try cleaning the MAF to see if it helps.
