I am having a somewhat intermittant problem with my '95 Ford Ranger XLT (2.3, 5 speed, 2wd). After driving it for a fair amount of time (20-30 minutes or so) the clutch pedal will get completely hard, and I am unable to depress the pedal. This makes shifting (and moving the truck) impossible. After leaving it alone for about a half hour, the problem remedies itself and the clutch acts like it should. The hydrolic fluid in the clutch reservior is at the level that it should be, and it is brand new looking. The truck has been maintained very meticulously, and has 124k miles.
I have not been able to find too much information on this problem and I would very greatly appreciate any input that anyone can provide.
Thanks
