I only just saw this. I don't have much experience of KTMs, but it sounds as though it runs rich and stalls, then needs lots of spinning over to restart because the inlet and cylinder are flooded with fuel.
My road bike does something similar, but only when cold and only if I pull away gently. It misfires and stalls and it's difficult to restart. Also I it will stall if I give it a rev to 6,000 rpm and let it drop to idle before it is warmed up.
In my case I think it's before the Lambda sensor warms up and the ECU is running open loop. It seems to me KTM often start with injection set a bit rich to be on the safe side.
