NH T6-165 Pto wont engage

[flitemedic]

The T6-165 powered down while doing lite brush-hogging, didnt shut off, just powered down to about 700-800 rpm and throttle didnt respond. In the middle oblong screen on dash showed "groundspeed PTO" (according to NH service mgr after sending him a "screenshot" of the characters. (2) error codes 3001(foot throttle sensor-signal not plausible0 and 3128(hand throttle-channel difference error). I shut it off and restarted, hand throttle worked and throttle pedal worked, but the lights referencing the gear youre in are out and pto wont engage)and pt engagement is electric. any thoughts?....Appreciate any input
