I have been having an issue with my 64 Bonneville Vista. It will start right up and run just fine but as soon as it gets to operating temperature it will shut off if I put it in reverse. Once it dies I can't get it to even turn over or click. I know the proximity of the alternator to the exhaust manifold heats the alternator up really fast and it needs to cool off before it will start again, but is the issue with it cutting out in reverse a separate issue? I bought a heat shield to put on the alternator and if that doesn't solve the problem with the nonstart, I might just end up going with a mini-starter. Any help or suggestions about the stalling in reverse would be helpful. Thanks in advance
