How old is your battery?
As batteries get older they sometimes loose their ability to maintain a full charge.
One way to know for sure is to unhook your negative battery cable when you're letting the bike sit for a few days.
By removing the negative cable you're preventing anything that may be pulling power out of your battery from discharging it.
If your bike fails to start after a few days of doing this, chances are you need a new battery.

Why did you replace the voltage regulator and stator? What symptoms were you having?
The most common cause of bikes not starting or dying is a bad battery but you didn't replace it. Without knowing more, it looks like you are simply replacing parts without correctly diagnosing the problem. That only wastes money.

Maybe a short
You could also have a short somewhere that is causing the battery to bleed down. One test you could do is to turn everything off, disconnect the negative lead from the battery, and then in dim light touch the neg cable to the battery.
If you see a spark, then current is flowing. If you have an ammeter, you could determine how much current is flowing, but most people don't, so then I would start with pulling a fuse and redoing the neg cable to the battery neg terminal. Keep doing that until it stops arking. Might get you to the circuit causing the problem. Won't cost a dime, and might lead you to maximize your troubleshooting.

Make sure key is off.
Pull the ground, set ammeter to amps range 20A or whatever your max range is on your meter. Hook meter in series between the negative post on the battery and the ground cable. This will tell you if you have a parasitic draw issue. You shouldn't have any discharge if you have the bike off and don't have a security system. If you have a security system you might see a fraction of of a mA draw but it should not be significant. If you don't have a parasitic draw issue its most likely the battery.
