As a neighborhood watch coordinator, I'd probably walk out there, photograph the license plate and casually but firmly inform him that I'm with neighborhood watch and ask what is he doing. Remain inquisitive and non-confrontational. Next step, report it to the local authorities as a suspicious unknown person in my neighborhood if his response wasn't acceptable.... Yes, I've done this before...
As soon as you ask "What are you doing", you ARE being confrontational. A better question would be, Hello their, my name is __________, and I am the neighborhood watch coordinator, may I assist you in your project, which is?
