Fuel caps have breather holes in them - once clogged the fuel tank is sucked vacuum and the engine stalls. Check the fuel tank cap for clogged breather holes.

As with any no-start or stall problem you will need to figure out if it is a fuel or ignition issue. The high idle usually means you have a vac leak or a problem with the throttle body or idle air control valve. The control valve is how the computer controls the idle speed. You'll need to watch the fuel system and spark to see which is being affected when the engine dies. You might want to hook a test light up to the coil to see if it is loosing voltage for example.
Just a thought! There is a provision where when fuel pressure drops the ignition is shut off. This is to prevent pumping when the fuel line is compromised. Monitor fuel pressure to see if it drops during normal operation.
raw gas smell is a sure indication of a fuel leak,,,the fuel filter on my ranger is directly under the drivers seat attached to the frame,,,crank it over and look under for leaking fuel,,,takes an inexpensieve tool to remove filter if thats where your leak is,,,the filter wont come off without the tool,,its cheap to purchase,,under 4 bucks,,doesnt matter if it wont start,,just crank & check for leak,,check under hood also,,,
first go to an auto partstore and have the code checked. most do it for free. could be coil, fuel pump, fuel filter, air filter or even a bad gas cap. but the dianogstic test should pin point the problem.
