FI bike, starts ok, dad running and cut out when hot

Friend with this problem, whats normal things to look out for check?

**symptoms
starts good no smoke or rattles then when it's get's warm run's bad then cut's out,restart when cool then the same again
all connections checked,all sensors computer say's yes,new filter/battery**

so bad running, cutting out when hot.
It is a fuel injected rotax single.

Ideas?

I thought this was going to be the sorry tale of a runaway bike and an injured father.

petrol pipe too close to hot components causing fuel starvation? blocked injector?

Regulator rectifier? Coil?

Sounds fuelly to me... although I did have a similar problem once on my old Triumph Herald... would cut out when hot and was traced to dodgy windings in the coil going open circuit when hot.

Oh just get him to hit it with a hammer...

Get it hot and check for spark and stuff, also check see if the plugs wet when it cuts out etc etc.
