I recently put a 350 in my 91 camaro rs 305. I got it running and driving today. I drove it for awhile and it ran fine. Suddenly out of no where it died on me while i was just idling. I figured it was the battery because it was making a ticking sound. I replaced the battery and got it started but it would not idle it would just die if I did not push on the accelerator. I then replaced the idle air control valve. That seemed to do the trick for awhile but then suddenly again when it was warmed up and when i was idling it died again. I tried to restart it but it would make the ticking sound again. I turned off my lights and it started but had the idle problem again. Also with the clutch pushed all the way in i could not put the car in gear. i don't know if that is relevant or not. i don't know what else to do. please help

thanks

I forgot to add i have replaced the ecm, the o2 sensor, idle air control, battery, newer alternator, coolant sensor, fan coolant switch, and spark plugs.
