I was flt ops engr covering an engine which occasionally displayed a "hangup" or interrupted accel on TO. We found it only happened during "zero bleed" TO's, and that turning on bleeds would clear the stall. So the recommended procedure was:
Leave bleeds on when taking the runway
Part throttle, watch for normal windup
Turn bleeds off for EGT/ITT margin
Push to normal TOGA setting
With a F/E onboard, All this could be done during a rolling TO without hassle.
