I am going through this exact same problem. My Rodeo (1993 4WD 3.2V6) has clutch hydraulic issues that come and go like the wind. I can drive it all over town with no problem, then go back out the next morning to find the pedal only halfway up and I can't get it to go in gear. Sometimes I wait a couple hours and go back and it's fine, just like it came off the showroom floor.
My vehicle DOES have 3 hydraulic clutch cylinders, despite 95% of the parts dealers telling me it doesn't. The Chilton manual says some of them have a third cylinder, which it calls a damper cylinder, but the Haynes manual doesn't even mention them. I even had to convince my mechanic it was there, and after he bled it, I had the strongest pedal I've ever had on it. This was after he had replaced both the master and slave cylinders. I have called O'Reilley's, AutoZone, Advance, and even NAPA, and nobody shows any damper cylinder or even a mention of it.
I was finally able to find a helpful parts dealer at Foreign Auto Parts in Hickory, North Carolina, who at first couldn't find it either, because it was not listed in his computer. But he took the time to dig through his paper manuals and after an hour or so was able to locate the damper cylinder.
So at the moment the damper cylinder is the only component in the clutch hydraulic system that hasn't been replaced, so that pretty much HAS to be the problem. If replacing that component doesn't fix my problem, I swear I'm going to trade it in for a yak!
