Bad gas -car may idle, but won't run well or kill with load.
Coolant bubble-air lock in coolant circuit, car over heats but stays running till something blows.
Air mix screw-Fuel air mix. adjustment, under left front plenum runner, w/ idle correct, adjust clockwise = richer / counterclockwise= leaner.
To do this adjust correctly you should have CO tester on test port at Cat. and O2 sensor disconnected.
Doubt any of these are your problem, please explain symptoms again.
Engine fires and runs to OP. temp?
Runs and drives to OP. temp. then just kills?
Runs and drives to OP. temp. until shut off?
What have you tried when restarting, throttle open, closed, 1/2 ?
Do you have fuel, spark, etc.... when attempting restart?
Do you have WSM?
Would like to help but need more info.
John
