Sounds like a possible crankshaft sensor, when they start to fail the resistance in the sensor gets too high, sometimes will manage to start but as the temperature of the engine (and in turn the sensor) increases so does the resistance in the sensor and causes an engine cutout, once left to cool down the resitance drops a bit and may allow the engine to start again. This would have to be confirmed with diagnostic equipment or by checking the sensor resistance, either way a job for the garage.
Then why does it smell like gas and try to start
If the check engine or MIL is not on and it does work, that is, it comes on during lamp test when you rotate ignition key from off to on, and goes out a few seconds later? Suggest it could be fuel flow or pressure.
If MIL light is on, then you need to have the engine codes read.
As to why you smell gas... significant amount of unburnt fuel/vapor somewhere (mikysfin crank) or an outright leak or evap malfunction but there again should be MIL light.
I'm not a mechanic but I feel like it's the fuel pump

I would start by checking fuel pressure if possible, tech tip.. have someone hit the bottom of the fuel tank with a rubber mallet while someone is cranking the engine, if it starts it needs a fuel pump.

I would start by inspecting and cleaning the battery terminals.
SOURCE: my kia just cranks and wont start sometimes
need to see it when it wont to start to diagnose the problem .one tip though and thats to keep the key away from a mobile phone ,or leaving key on top of the tv .the magnetic bar code can be affected by a strong magnetic field signal
SOURCE: my dodge neon 2000 stalls after about 20mins
You might have a bad coil pack causing the engine to stall after it gets hot, I would start with changing the coil pack, good luck, Gary
Testimonial: "Good if it works .... will try"
Check the fuel line pressure it may be low should be 55lbs
replace the crankshaft position sensor
