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.

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.
