Hello, my name is Bobby. Thank you for the question. It sounds like you can have one of a number of issues but most of the time this happens when the fuel pressure bleeds off. This happens when either the fuel pump is failing or if the fuel pressure regulator is failing. One easy thing I would do first would be to clean the throttle body. If that does not help then you need to see if the fuel pressure is bleeding of when the vehicle is shut down.
