I'd have the charging system checked. Also have the batteries checked independent from one another (cables disconnected from both). Also make sure your battery cables (all ends) are clean and tight. Additionally, you may want to look at the fuel heater element inside the fuel bowl and make sure that the element is still attached to the pads on the plate. If the fuel heater is shorting, it will usually blow underhood fuse #22, but not always. If the element is loose, disconnect the element from inside the fuel bowl and see if the problem goes away. Cheers!
