1964 Eldorado Convertible stalls while driving.

[Joseph Pagliuca]

My 1964 Eldorado convertible stalls while driving.  It completely goes dead, it will not start up right away. when you turn the key there is no sound at all.     After sitting for about 5 minutes, turn the key and the car starts right up.  Already replace the fuel pump . It still happens.    Does anyone have any idea on what may be going on?

I had a similar problem a few years ago. In my case it turned out to be the ignition switch. From what you describe it sounds like an electrical problem. Check ignition wiring. connections, components, battery cables, grounds,  etc.

If you dont know the age of the battery cables, just replace them.  At the ignition switch, check for blackened or darkened connectors. That indicates a loose and heated connector.  Check the connector to the bottom of the fuse block also.  Connection at the battery terminal on the starter needs to be check as well.

At full speed. It starts to sputter then shuts down.
