according to the owners manual it is called "batt fuse" It is under the hood in the bank of fuses located toward the rear of the engine compartment.

I have checked all the fuses under the dash and under the hood and this is the only one that the excessive draw changes on. I just can't find anything to show me how to trace it to the source of the leak.

So is your battery just going dead while sitting over night?

Yes sometimes before overnight. i.e. I park it at work at 9AM - If I don't start it by 3PM it will not start at 7PM. Have checked voltage on charger and if not charged overnight it loses at least 20 percent of charge

I have even seen window switches cause parastic draw before so sometimes you really have to check everything.
