I could be wrong but it sounds like you may have a problem with the cold
start injector or thermo time switch.  The F.I engines are notorious for bad
cylinder head temp sensors as well.  I would try shooting some starting
fluid in the air cleaner when the engine is cold.  If it starts right up and
dies then lack of fuel is your problem.
