if the fuel system is not venting properly, you could run lean - if she dies, after checking the fuel pressure then loosen the gas cap and see if the "whoosh" happens again and if that helps her re-start. a simple test, costs nothing... the fuel-soaked gravel, pointing to fuel leaks are worrisome, as the fuel injection system is at a fairly high pressure and a pin-hole leak from a loose fitting or cracked hose can squirt a bunch of fuel quickly. please, please don't check with matches! s30 driver and i were working on his car right before he left for a long trip and just wiggling his fuel rail caused the injector hoses to crack (they were old) and it was spraying fuel all over the place. the fuel leak may or may not have anything to do w/the stalling, as the pump may generate more flow/pressure than the leak, but it's still something that needs to be addressed. if i recall from early posts, your fuel hoses have been replaced by a previous owner - the hard lines come up the body on the passenger side right under the battery, and many have found corrosion on them due to leaky batteries over the years - worth a check.
