Thanks. The thing is that it seems more like a computer glitch or something. I only smelled the gas smell that one time when it wouldn't start and the truck runs fine 99% of the time and when it dies it starts right back up and is fine afterwards. Could an actual mechanical problem like a clogged fuel filter or injectors or leaking intake manifold or something cause such a highly intermittent symptom? I'm in the same boat as the other people that don't want to just start replacing expensive parts in a car that's fine almost all the time but just dies out of the blue once or twice. But it is scary.
