Default 97 ranger 2.3 5 speed clutch goes out at time when warm

My first time to try and solve a problem with my 97 ford ranger 2.3 cyc 5 speed. I seem to be able to drive it most of the time without incident, but if i start having to pull a few grades and it's warm outside my truck seems to heat up then starts losing it's clutch . Once it reaches a certain i guess temperture it total has no cluthch. As long as I can find a incline to start to get it moving I can usually make it home . But until it cools off it will not even move in gear . At this time also clutch pedal real stiff.After letting it sit for awhile it's back working again.

Heat may be causing binding of the throwout bearing so it does not return to the 'rest' position, and keeps the pressure plate from grabbing the clutch disk as it is supposed to. The stiff pedal is a hint, I think.
Solution is possibly clean the clutch parts and the input shaft cover that the bearing rides back and forth on. It may be the bearing is carried by the hydraulic cylinder that wraps around the input shaft, but either way, I think cleaning or replacement are in order. You may be able to gain access to that area if there is a port on the side of the bell housing. Of course if you use some brake cleaner spray, you may lube the clutch disk. Eh, I don't know for sure. The other method involves removing the transmission and bellhousing.

Thanks for the information, Its kinda hard for me to get under the truck (age) so I'll probably have to wait on some help to try an access the area your speaking of. Here's a kicker, never have seen a leak of any fluids and I swear the transmission looks new, I just bought the thing in February. When I first got it home i noticed the coolant reservoir fluid looked filthy, so I figured I'd flush the radiator and clean the reservoir. I tried empting the radiator by opening drain plug , not a drop came out so I applied water pressure with a hose , nothing , then i tried fishing a wire into it to maybe unstop it ,no luck. So I emptied radiator by disconnecting bottom hose. I then put clean water and new coolant in ,I changed bottom hose out put new radiator cap on. I drive it now and it starts getting warm not super hot but hot enough to where you can smell it and gauge goes up almost half way. Then if i pull a lot of hills that's when i feel I'm losing the clutch and if i get stopped on an incline , it wont engage i can't move unless i can get some momentum going.

"They" say to test a clutch for slippage, select direct gear, and floor the accelerator while traveling 30-ish mph. If the engine speeds up, but you don't seem to accelerate, your clutch is likely slipping. If you do that test when things are all heated up, you know something is causing slippage per their definition.
If the throwout is binding on the input shaft collar, you might be able to use the lever hole in the side of the bell housing to squirt some brake cleaner on it.
I don't know other causes, except perhaps if you had contaminated fluid in the clutch system that was boiling(hot) and expanding, causing the slave cylinder to apply pressure leading to clutch slippage. Just another to add to word salad for today.
If you flushed the clutch hydraulic system, it may prove interesting.
The report on the radiator would make me suspect a lot of sludge in the cooling system, especially at the bottom of the radiator. I would expect there is also some in the jackets around the cylinders, and some settled in the cylinder head. Perhaps a "prestone style" reverse flush kit that allows you to use a garden hose to back flush(reverse normal flow) the cooling system is in order? It flows water through the heater hose(core?) backwards and allows the water flow to exit via the radiator cap opening.

FWIW, when my truck was new, I thought I had a locked up clutch. After sitting a few days when it had been raining, I went to drive off, and after starting the engine, I couldn't get it into any gear. The clutch was not releasing. I finally put it in 1st, I think, and started the engine. There was a lurch, and the clutch released, working fine as far as I knew. That happened once or twice more to no big result.
Quite the opposite of your situation. Age should just slow you down, not roadblock. I find getting up from working on the floor, or bending down to do lug nuts is more difficult, but figure vertical and above ground are a good result these days. tom
