no warm engine start

[mistry]

89 bronco II. It will not start with a warm engine and has begun to die without warning while driving. I can smell gas, and have had the injectors and pressure checked.What is the most likely culprit?

Welcome to this forum! It might be a leaking fuel pressure regulator, injectors, or the engine coolant temperature sensor or air charge temperature sensor being out of spec. Do you have a check engine light? First start with checking the fuel pressure with the engine running cold, then when it's warm, and starts to act up.
