Weird issue 95' KA24DE

[second_chanceS14]

So lately my car dies on me randomly. I did notice in the mornings sometimes the car tends to smell like gas but the smell would go away, car ran fine and everything but if i shut it off after a casual drive it will start then the idle will drop below 500rpms bogg then die. I normally have to wait 30 to 45 mins before i can get the car to start. Ive tried different MAFs, cleaned the throttle body, cleaned the air filter. My distributor cap and rotor were switched a little under a year ago and i have denso iridum spark plugs which i got back in 09 but these are supposed to last 100k which i know i haven't exceeded. Now i looked at posts that talk about idling but my problem is only after i shut off the car and try restarting it, once its running it runs normally. Could this be a bad injector maybe that stays open and by letting it sit there it allows the fuel to evaporate ? bad fuel filter? although it was replaced 4 months ago?? Any suggestions and input is highly appreciated. Thanks
