check for a vacuum in the fuel tank that is preventing the pump from moving fuel through the system. Air should not flow freely through the manifold as there is a regulator in the system that maintains the fuel pressure for the injectors. It should stay shut for a pressure of around 50 psi before it allows the air to flow out
Get a DTC scanner and see what it says...in the meantime, check that fuel pump relay and fuel pump. The humming sound is probably the heater blower motor or part of the HVAC system winding down after disconnecting from power.
Sounds like you have a small bit of dirt or grit in the fuel system when accelerating it is drawn with enough force to cut off the fuel supply then is released when engine at Idle. 1 run liquid fuel line/injector cleaner in 1 tank 2 check fuel lines for debris 3 change fuel filters 4 have fuel tank flushed here is trouble shooting order less expense to greater.
