Default 98 cherokee P0340 P0320 P1391 problems

Hello all!

I'm currently having a Serious bug with my 1998 jeep cherokee, IL6 197000 miles on it, I'm have intermittent lose of crank sensor codes and crank sensor circuit codes coming up from the computer. Here's a list of performed items

Distributor
Distributor cap/rotor
Engine retimed
Crank sensor replaced. (Genuine OEM)

I'm at my wits end with this thing. It bucks at high speeds as well. I was told by my mechanic it could be the timing chain but not sure what to do. The codes listed in the header are in the order the OBD2 code reader is reading. I have so searched this forum for a solution but to no prevail. Any help would be GREATLY appreciated. Thank you!

Have you thoroughly inspected the wiring for the crank sensor?
