too hot only affecting mid range?

[auto2]

yes I reprogramed it the first time it happenned and it immeadiatlly fixed it BUT it may just of been a cool down time thing andnot the reprograming. You can hold it in the air and move the throttle and nothing happens untill almost full throttle . steering works at same time throtle doesn't.
I even tired no brakes and no reverse and no difference.
I am also using mechanical brakes and disconnected the brake servo and just ran motos brakes as a test and it seemd to take longer before the "problem".
