Try disconnecting the battery overnight straight after a good run to see if its a poor battery (won't start in the morning) or a drain from the battery (will start in the morning).

When you say the alternator is showing good power - please explain.

It wont drain through the starter.

With that degree of discharge (you mention afew hours) i would put money on the diode pack in the alternator being f**ked.

Is the body of the alternator warm to the touch after being stood for abit?

If so....bingo.
