I have a 2003 GMC Safari it died while driving and won't start at all what could be the problem

We would need a lot more information. Bad battery connection or fuel pump would be my first blind guesses.

What happens whey you try to start it?

Could be out of gas

May be a long shot, but when that happened to mine when driving it ended up being the distributor rotor falling apart. The POS was a fairly new AC Delco too.
