91snatch

i have a 91 civic dx hatchback. when first starting, it seems to be missing but comes out of it within 10 seconds. it runs and drives just fine after it comes out of it until you shut it off again. after driving it for awhile i shut it off and wait about 10 minutes to start it again and it wont fire at all. after about 3 times of cranking it over it will just barely fire and finally run. if i leave it over night and start it in the morning, its just fine. i replaced the spark plugs and cleaned up the cap/rotor. plug wires look fine and the old spark plugs didnt look bad either. i think it has to be an electrical or fuel issue but just wanted to see if anyone else had the same problem. opinions please
