It had to happen sooner or later....

Running fine and the bloody thing cuts out. No warning. No coughing or spluttering. Just cut out and died.
It turns over on the button, but won't fire and there's a nice wiff of petrol, so I've not filled it with diesel

I'd cleaned it about an hour before and had done 20+ miles on a fresh tank of juice.
Anyone had similar or any pointers?
