If the halibut is thick, you'll never get the center done before the pancetta is burnt. Instead, try this: preheat the oven to 425F. Saute the pancetta-wrapped halibut just until the pancetta has browned. Then move the whole pan to the oven and roast until the interior of the halibut reaches 135F. (Use an oven-proof pan, of course)

Even my son - who dislikes fish - cleaned his plate. The pancetta added a smokey flavor to the halibut.
