It sounds like after your carwarms up it wont start. Is it getting spark? Are your spark plugs wet from fuel? If your not getting spark i would look at your coil. Unhook fuel line when it wont start and crank to see if you are getting fuel, be safer to use a fuel pressure gauge. if you are not getting fuel switch fuel pump relay with another relay in your car that is the same and then see if your getting fuel. If this doesn't work let me know and I will give you some more way's to figure out what is wrong. Hope this helps!
