Fuse problem

[Skinner]

Riding last week and the sled just quit. No power to anything so I towed it home and found the 20 A. ignition fuse. Replaced the fuse, went back out and about 20 miles later it quit again. This time flashing code 43. Researched that code and found it to be fuel delevery system. Checked the fuse for that and it was blown. Replaced that 10 A. fuse, and 10 miles later it blew again. I wanted to ride so I put a 15 A. fuse in and it was fine all day(put 120+ miles on with no problems). Does anyone have any idea what the problem might be? I ride a 08 FXNytro RTX. Any help would be appreciated.

Do you have any after market wiring on the sled?

No the sled is bone stock.
