kubota u10 5 not starting at all

[AdamDesign]

Hi, my mini digger, has working all day ( its 2 years old). Stopped the engine for 10 minutes. Went to restart, put key in and turned, the engine cranked, but did not fire. Engine stop fuse had blown, therefore changed, went to start again, no joy. Turned over, couple of times didnt fire, and now, no ignition lights or any electrics. Charged battery fully. Tried jumping. Any help or advice would be appreciated. thanks. Herts UK
