The '78 cars dint have the lock-up trans originally. I already considered that, and that's why I asked if it felt like something was dragging/lugging the engine down at a stop. A stuck lock-up is similar to trying to stop a standard transmission car without pushing the clutch pedal down.
A non-lock up 350(which is what the car should have) will have no electrical connections on it anywhere. The lock-up 350 will have a connector on the driver side of the trans, just behind the shifter shaft. IF the car has a lock-up style trans, even without any electrical connection, the lock-up
could be applying due to a stuck valve, or a hydraulic leak in the circuit. Even so, this would
lug the engine at stops, not shut it down instantly.
The mystery continues....
