1993 Jeep Wagoneer hot start issues

I just got a jeep wagoneer and iit drives fine till you stop after about 20 minuest of running and then will not run. First startup runs fine and charging system reads 14. After the 20 minuest or more of driveing it we turn off and get out. We let it sit for a few munests then try to start it and it runs rought and then starts stumbleing and dies. We lest sit for about 2 hours and then it will run and start up fine. Also I notest that it is hard to turn and wheels lock up on back or front when cornering. Like some posy track gets engaged. This is also fine in the morring but after it heats up it will start to acked like the posi is engaged.

I have repaled the plugs, wiers, and battery.

Also the charging system reads lower and lower as it heats up.

I need truble shooting checklist for engen monitoring parts. Like crank position sensor, air intake, maniforld, Throtal bodey.

This is a V8 5.2 with MPI.
