i had a similar problem on my old 92 rs that had a 305 tbi.. but my problem was the coolant sensor went bad it eventually got to where it wouldn't start at all but i would check your codes it might tell ya whats going on.. hope this helps..

K , could be a dirty fuel filter ... leaky injectors .. dirty IAC ( sticky ....) EGR maybe Also the CTS sensor.

Does it do this ...starting first thing ? Or does it have to be hot to get this condition ? Any codes ?

it has a new filter,,injectors not leaky,,iac new,,cts new,,it does it after first startup after it has been sitting over night........I did hear somewhere that the crankshaft sensor might be the cause any sugestions

Check resistance on your injectors, if you have multiple bad ones it will cause the computer to overheat and basically shut down. also could possibly be ignition module under distributer cap autozone can check um out.
