Hi there. Are there any warning lights on? If there are any warning lights, this could lead us to the possible cause of your concern. However, low fuel pressure could be the cause. If there is not sufficient pressure in the fuel line, then the fuel system cannot deliver enough fuel to keep up with the demand. Imagine if you will, turning your garden hose on full stream and squeezing the trigger on the sprayer; it provides a good spray. Now, if you turn the garden hose on only a quarter, how does the stream/spray look now? The nozzle won’t have enough pressure to provide the same spray you have when the hose is fully on. Water will come out of the nozzle, just not as much as when the hose is fully on. The same thing applies to fuel injectors; if the demand increases, as with acceleration, there needs to be sufficient pressure in the line to allow for this change. A few other things to consider would be the air flow meter, the manifold absolute pressure (MAP) sensor, the throttle position sensor, and the engine control module (ECM). I would suggest having a qualified technician, such as one from YourMechanic, perform an inspection to diagnose your stalling problem and to avoid any unnecessary part replacements.
