Timberwolf TW 150 randomly shuts off

[MarkusB1994]

Hello guys, 

my 2003 TW 150 shuts off randomly. It happens in idle, high idle or full throttle. Sometimes only once in 2h hours, but also every 10 mins. The engine can be started immediately. When I’m fast enough and the engine is still reving down, I only have to crank it for half a second and it revs up again. 
Not like it the coolant is too hot and you have to wait.

The filters and fuel lines have already been cleaned.

Does somebody have an idea what’s the issue?

When it shuts off, is it an instant shut down? Like you have turned the key off? Or does it die slowly?

Like turned off with the key.

Check wire on fuel shut off. 

Could be ignition barrel is worn a bit and works it's way off.
