That is a sign of a fuel leak. The FI system is not holding the pressure after the engine stops. Could be a bad check valve in the fuel pump which requres a new pump, or one or more leaky injectors, or a bad fuel pressure regulator, or an external fuel leak. Satart looking at the easy stuff first and the fuel pump last.

Well i replaced the Fuel pump and fuel filter, and i dont think any hoses are leaking, so that leaves check valves, fuel pressure regulator and leaky injectors

I had that problem when one of my fuel lines split. Somehow a stone got kicked up from the road and put a hole in the line underneath the drivers seat, didnt show much effect untill I tried to start the car the next morning.
I just got a fuel line repair kit from autozone for $20, easy fix in my case.

I would definitely check everything, it could just be a bad line somewhere... I would do a visual/smell check while running to check...
