Mercury 200 EFI 0T272390 2001

engine always starts and runs good at cold start up. Whenever I go to start it after those runs it always does the same thing. Engine starts missing and eventually will die and not restart. Every time I have learned I can unhook #5 CDM and it will start but run rough. Ive replaced every ignition part I know of except the ECU and detonation module. All CDM's, Stator, Trigger, regulator/rectifier's, plugs and checked all grounds multiple times. I'm about to give up.
