you need to figure out what missing at the time when the car acts up again.

when it dies on you again, you need to check if you have spark, if you have spark, then you might wanna check the fuel pressure of the car also listen through the gas cap hole to see if the pump is working.


if both are not there, then you might have a more involved problem such as main relay, crank sensor acting up, cam sensor issue, etc.

or maybe with the mileage that you have, the engine might be tired already. compression test


i missed your fact #3, after reading it, i think your problem is somewhere in the key cylinder switches.
