the starter is probably going bad on it when they get hot the brushes pull away from the starter motor,and this causes it not to get enough voltage to turn over,once it cools the brushes return to normal,you need to replace the starter to make this one start good all the time,those are good little vehicles ,and have an excellent 4 wheel drive system in them,good luck on it.

Assuming it cranks but will not start...
This is more common on a carbureted engine and there's a lot of mileage or wear and tear. The choke will set when the engine is cold and the choke will be "off" after the engine is hot and this makes the fuel/air mix very lean. Some older cars will benefit if you set the idle adjust screw to run a little richer in Summer and then lean it back for Winter. If the engine compression is very low from wear and tear this condition can only be fixed by rebuilding the engine or swappin git out with a rebuilt engine where the compression will be back to specifications.
Sometimes dropping a new or rebuilt carburetor in will fix this problem if you are confident the compression is good.
On fuel injected models there are some vacuum activated switches that can affect the fuel/air mix when it is very hot, too. The other thing to check would be fuel pressure to make sure it is within specification.
Low oil pressure will affect this too on a very worn out engine.

As electrical wires and parts get hotter, the resistance goes up. Odds are if you replace the starter, or at least the solenoid, your problems will go away. I bet the starter has been on that car for quite a while now and needs to be replaced. Just got done replacing the starter on my car about a month ago. Same reason.

sounds like possible a bad starter. have dealt with the same problem on every gm vehicle i have owned due to them having the solenoid mounted on the starter near the exhuast. not positive on that vehicle but may be worth checking into

Replace the starter. Also check your ignition timing.
