Won't start when hot? R & R the starter. Excessive heat can affect the magnetic field of a starter motor.
Won't stay running? R & R the fuel pump. Jeep are notorious for poor fuel pumps.

Had the same problem with not running when hot. The AIS motor was changed out at at total cost of 162.00 and not a problem with that again. Just spent $900 + on AC coil. Now at 6700 miles. Previous owner did the same back in 97 at 26000 miles.

There is what they call a heat shield on the starter. The symptoms you described are the exact same symptoms my SAAB experienced when the mechanic failed to put the heat shield on the starter. Check yours and see if the starter heat shield is in place or if it is worn.
Starts fine cold... but after the engine warms up... or when it is outside... it takes several turns of the key to get any activity.
Sounds like your starter is over heating! If this happens too much... one day you won't be able to start it at all.

Try checking the crank sensor located on the left side of your transmission bellhousing...

Have you checked the timing, or had a tune up in recent history. Often if the ignition is advanced to far, it will start fine when cold, but not when hot. Have the shop set the INITIAL TIMING and not the advance.

We recently bought a used 94 Grand Cherokee and it would die while driving, usually it would be a rather warm day. If we let it sit for a little while it would start back up for us, took it to the shop and had them test it. They thought it was the crank sensor, couldn't get one right away so they attempted to put the old one back in and it would not even start again. Haven't had any problems with the new one, it sounds like your crank sensor is in worse shape than ours was. Hope this helps.

Your crank shaft position sensor could be the problem. There is an oxygen sensor that has been known to cause the Jeep to not start when it is hot.
Over all the Jeep is a good vehicle. It is a typical junk pile.

Any advise on how to replace the antenna? It is a 1994 Jeep Grand Cherokee Laredo.

I know this seems random and probably unrelated to your problem, but I had a similar problem on a 1953 Chevrlet pickup truck I rebuilt back in High school, oddly enough it was just the batter. Go have it checked and don't assume the little "eye" is accurate.
