Thanks for the reply, Peter. Will check the vac lines, leaks and the idle control valve. Sounds like a good place to start.

Specific to the cause of this problem... What controls fuel flow after startup, when engine is warm and/or what would cause the fuel flow to stop after the initial startup fuel delivery... and why only when warm? No hesitation or sputter, just a clean quit. < Like when Grandpa turns out the porchlight!! >

Wait a darn minute...could this be electrical?...ignition?

BTW..new plugs, ignition wires, rotor, cap, less than 5000 miles ago. Checked today and all are OK .
