Re: 99 Taurus se 3.0 will not start after warm
A crank sensor is a possibility. If you haven't had a tune up done in the last while I'd get new plugs installed and the timing checked. Also get the cooling system checked out. An engine that runs too hot can cause the engine to go into what's known as a 'safe mode' so it doesn't cause damage to itself from overheating.
