2000 f-350 7.3l TD electrical problem

I have a 2000 f350 7.3l turbo diesel. 3 days ago I started it and it idled for about 15 seconds and quit. I found a 30 amp fuse blown. It is in position 30 in the under dash panel. The manual says it is 'Fuel Heater, Wastegate Solenoid, Injector Driver Module Relay Coil'. I replaced it and everything was fine. Today it blew again, so I replaced it but now it blows when I turn the key on. BTW it is 15 degrees out this morning and I keep the truck plugged in overnight. What can I do?

There is a fuel heater in the bottom of the fuel filter bowl. Common problem for them to break loose and short inside blowing the fuse. Can easily replace it can also unplug it on outside of fuel filter housing to replace fuse and drive truck. Many people never fix it.

+1 on this pull fuel filter cap and you will see it on the bottom all rotted and broken away shorting to the housing.
