1990 Civic LX 4 Door

my car keeps shutting off while idling, never while im driving, after it shuts off it wont start again for about 30min or so and then if left idling it will eventually shut back off.

i purchased this car about 2 weeks ago and this problem was happening then, i replaced the spark plugs, distributor, spark plug wires and the main relay immediately and then would let the car sit and idle for a while and it didnt shut off so im thinking problem solved, today i was cleaning the car out with it running and it shut off on me.

Any suggestions on what it could be??? i need this problem fixed asap, any help would be greatly appreciated

Does the idle fluctuate before shutting off?
Does the idle drop then struggle before shutting off?
Is your check-engine light on?
Is your car carbureted or fuel-injected?
Have you tried cleaning out the IACV, if you have one?
Have you replaced the fuel filter?
