Warm dying at idle and start problems are indications of an engine with low compression. Did the dealer give you any detailed information as to what is wrong? Any compression numbers? You haven't given us much information to go on. You can try replacing the ignition components (they don't come with a rebuilt engine anyway), check for engine codes in the PCM, clean the MAF sensor and check the catalytic converter to see if it clogged.

 

It really looks like an engine issue combined with sub-optimal maintenance.
Sorry to see that happening!

 

have you ever had the battery or starter checked or replaced?
