If the vehicle starts when this happening by just adding a fuel source then it is not the ASD. The ASD not only controls the injectors but it controls the ignition coils as well. Also, if the ASD shuts down the engine, it will set a code so we can confirm this by checking codes.
If this is just low pressure or no fuel, then I will guess you don't have any codes. However, let's go ahead and check for any codes just to be sure.
If there are no codes, then we need to hook up a fuel pressure gauge and find out what the pressure is when this is happening.
When you replaced the fuel pump, did that come with a regulator as well? I am thinking you have an issue with the regulator is it was not part of the pump. It sits on top of the pump and can be serviced separate.
Let me know if there are codes and if you put a new regulator on with the pump. Then get a PSI at the rail when this is happening, and I am sure we can figure this out. Thanks
