starts fine when cold but after getting up to normal operating temperature and getting shut off it will not start(still cranks and turns overbut will not fire up) unless you wait 10,15 or 20 minutes.
My 96 V6 has started to do the same thing. It happens so intermitently that it won't do it for my mechanic. When it does do it, it sounds like what you described is happening to yours. Let me know how you fix it. Good luck.
