Please Help!

I have an occasional no start problem that is becoming more frequent in my 1991 Si Prelude with an automatic. I beleive it must be a sort of relay problem or trans electrical. Other posts suggest a main relay problem, but do not exhibit my same symptoms. Here goes-

On occasion it would crank but not fire at all. If I turned off the key and tried again it would fire right up. It progressed to trying the switch a few times and now many. I have also realized that before a successful start(when ignition switch first turned on) the "S3" shift indicator light comes on breifly with the other lights and then goes out. When it does not start, the "S3" light comes on then continuosly flashes. Whenever this light flashes the engine will crank but never fire. I now find myself turning the key on and off numerous times until the light goes out instead of blinks, then it will start right up. This has begun happening daily and takes 5-15 mins sometimes.

Another symptom or problem may or may not related, but be of help in diagnosis. A very few times in the past the car would start then slip terribly in gear. The "S3" light was then flashing also. I would pull over, shut off the car, and then restart it. It would then drive and shift normally.

Any help is greatly appreciated. Thanks--
