Hi there - I would check the fuel pressure with a gauge to see what the pressure on the fuel rail actually is. If pressure is low, the problem may be with a clogged fuel filter, failing fuel pump relay (not passing enough current), or a weak or failing fuel pump. I would recommend having a car is stalling inspection completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
