That is what it sounds like too me. A fuel pressure leak down test can tell you for sure if that is the case. Sometimes but not always a good injector cleaning will stops this if you want to go that way. After you get it fixed, I would recommend running a top tier fuel, something like Chevron or Texaco, and for times you can't get the good stuff keep a bottle or two of Techron around and put it in the tank. My old Tahoe had a problem with one of its injectors, as long as I ran Techron fuel it ran just fine.

Might be crank sensor , sometime when sensor gets hot won't start till cools down

There's also a good chance you're throttle body just needs to be cleaned out. I had the same issue with my car recently, except I don't know about the smell from the exhaust. Get some BG cleaner for $10, that's what worked for me.
