1970 Super Bee 383 Auto Stalling when hot

[eldubb440]

if it starves for fuel after running for a couple miles, wouldn't it "sputter"? ........ he said it doesn't sputter, it just cuts off

My moneys on a failing ECU

Not sure if this problem is being discussed in another thread. Bought a 1970 Super Bee 383 automatic. Took it out yesterday. drove 5 miles to gas station. Put premium in then drove another 4 miles (45 mph). The engine just shut off going up a hill. Had to coast to the side. The car started back up and I drove another 4 miles when the engine shut off again. Got stuck on a two lane. Started the engine and limped back home - 1 mile at a time. the car would start back up but only go about a mile. At one point I was able to coast off the road. Sat for 5 minutes then made it about 3 miles. Finally got it back in my garage. There was no hard idle or sputtering. It would run normal then shut off each time. Any ideas where to start looking?

Boiling fuel

Bad coil. It fails when it gets hot. The engine quits like you shut the key off. Fuel problems will usually sputter before it quits. I have had it happen on a couple of my cars.

I'm thinking either ECU or coil myself.
That's were I would start looking cause that's easy to test

Check the coil, simple resistance measurements. Then take a look at the fuel pump pushrod. Some aftermarket rods wear quickly. Daughter's 69 Charger had one, no sputtering, just died in the middle of the freeway.
