When the Inquistor attacks Fenn Rau does Fenn Rau get an extra evade die? I only ask because if the Inquistor turns off autothrusters would he not also be at range one of Rau?

No, he does not get the extra die, according to the FAQ:

Only the range of the attack is treated as Range 1. Any abilities that reference the range of ships, such as Carnor Jax or Scum & Villainy Boba Fett, are not affected by The Inquisitor’s ability.

Thank you
