Default Bucking/hesitating

Bought a 99 durango (sorry, I know this is a Ram forum but it's the same engine anyways) 5.9L a few weeks ago and had discovered it had a bit of a buck/hesitation that seemed to happen most often at highway speed but sometimes when trying to accelerate up to highway speed. Scanned it and it threw misfire codes for all 8 cylinders. I thought ah that's probably an easy fix with a tune up. Replaced all plugs, wires, distributor cap and rotor, and a new coil. The next time I took it on the highway it still had the problem. It doesn't do it the whole time but on a 45 minute highway drive it did it for about 5 minutes. Scanned it again and now it throws code 1391 (intermittent loss of CMP or CKP) with no misfire codes now. Think it's the same original problem? And will a new crank sensor fix this or should I look into something deeper?
