Question about 2000 Jeep Grand Cherokee
The first thing I would check is to make sure battery is securely tied down, cables are connected, and in good shape. Sounds basic but it has caused this problem for many of us.

Sounds like an electrical issue when it gets hot. I've found several similar issues regarding the PCM, but this can be an expensive attempt to fix it. Some reported electrical shorts with the mounting screws causing it to die.

usualy you will only have two tires spin at a time even in 4 lo or 4high. those tires are going to be diaginal from each other tipicly. now since your vehcle is equiped with quad drive it may employ a limited slip rear differential to help it along. however this only afects the rear axle. now you can test it by jacking your vehicle up and setting it on jack stands. one for each wheel onder the axle tube on a good solid (concreat or black top) flat surface. then have some one you know and trust to get in the car and put it into drive . now you can actualy see what wheels are spinning or not.now is were the limited slip comes in if you have one rear wheel spinning and the other is sitting still the limited slip will engage and start the other wheel spinning . now this may bang until the other wheel catches up (note that the faster the wheel is spinning the harder it is on your truck)now be very carfull stay away from the wheels tires and all other spinning parts it is a machine it can hurt you badly. but give it a try and it will answer your question. be safe hope this helps

You likely have it repaired by now but it sounds like a classic case of oxidized battery or cable connection (sometimes mis-diagnosed as bad battery but cured with new (clean) battery)

oil pressure problem should be checked independently of other problems...Use a good accurate mechanical gauge to check. If pressure is good (no less than 15psi at idle hot (I prefer to see at least 20) check dash grounding, block ground and if OK, change sending unit. Dash and body ground can influence operation of shift and body control modules so indirectly your problem may or may not be related, depending upon what you find while testing. And it could turn out to be a defective module! They are expensive and just plugging new ones in may work, but then again, it might not. I might be totally incorrect on this...that's the value of actually being there instead of doing this by "remote control".
If you read the numerous posts pertaining to all vehicles, you will see that you are not alone with electrical problems...As long as the engineers who design this stuff, keep using "modules" to replace ordinary simple and reliable systems, we will continue to have these problems. Do some testing and I'm sure you will find a solution! (I'm still waiting for someone to make a program for a PC that will give a complete readout of every system in a vehicle, including exact faults instead of general system "suggestions")

Sounds like the ECM....the computer that controls all the electrical functions on the car is having some major issues or needs to be replaced. A auto repair or auto parts store should have a diagnostic machine that will tell you for sure or you can purchase one for between $50 and $150
