Super Bee JC

Appreciate any help. 1970 Super Bee 383 auto. Low Miles. New gas tank--New Carburetor-new filter-new Distributor & Coil--- Car starts up good. Runs good for about 30 minutes and then starts to break up. Ran it on the highway for 20 minutes between 50 and 70 mph and it performed and sounded real good.Timing and idle reads good. It gets to a point that it starts breaking up and stalls when you stop. It does starts right up but when you hit the gas pedal it stalls out. Need to play with the pedal to keep the engine going. Thanks for any input.

Right before the car stalls, does it do anything weird? Like buck, surge?

Alot of guys are experiencing vapour lock with the new gasolines and any of the original fuel lines near any heat.

Coil might be getting hot. If it lies on its side it may thru the years have lost the oil it uses to cool itself.
