I've got a custom auto sound stearo. I have my memory connect to b+ on the fuse box. Now when I crank the car to start it, it loses that connection and the memory gets reset. Its not a lose connection, becuase it remembers the CD somestimes, just not when i crank it over. Like If I'm listenting to it on 'start' then turn it it 'off' then back to 'on' it remembers fine. Just when i crank it again, it loses it.

You could either have it connected in the wrong spot (that I doubt as I have not seen cars with a 12V terminal that has power in all key positions except when cranking the starter) or you may have a problem with the voltage going below what the radio needs to retain memory. Most radio's will work between 8-15 volts and while you are cranking that line may drop down below, let's say 8 volts and long enough for the memory to clear.
I have seen car with bad voltage regulators to where the voltage spikes above 15 volts and the radio cuts out from too much voltage.
