Movie about cold killers hunting a child?

It must be a late 1980s or beginning 1990s American movie.

I think the plot is that some gangsters/killers want to kill a little boy.

There is a scene in which the kid is in a house in an open field, there are two or more bodyguards protecting the kid, one inside, other outside. Finally some killer(s) kill the bodyguards but kid escapes and runs on a highway (? not sure about that though).

Sorry not much info, I have only these images in my head, I remember it was quite scary the way it was made (I was young at the time), since I never found the movie, I have searched quite a bit on Internet but no success.
