I had this problem a month ago, and thought I had it fixed; but apparently not. After about 1 hour of driving, my clutch pedal went to the floor without activating the clutch. ( 2.8 with 5 speed) There was no loss of fluid, no leaks evident, and the slave is a new Dickman 2 seal unit. I noticed on the F40 ( 86 Fiero kit car) the heat shield for the slave had been removed. I assume that this was done because the builder had installed two good sized cooling fans in the engine compartment blowing air forward, and venting the heat out the rear window louvers. I installed a heat shield between the slave cyl and the exhaust downpipe nearby, and had no trouble for a month. The shield was one off my 86 parts car. The issue resurfaced yesterday after a longer than normal spin around town. With no leaks, I am assuming heat is boiling my clutch hydraulic fluid, causing fade (let the car sit 10 minutes, and the pedal is normal and functional again) , and that the metal shield by itself is not adequate. I am now looking at insulating heat shield material. Has anyone experienced this, or have any suggestions? Thanks in advance.

If this is a stock 2.8 I would remove those fans the previous owner put in maybe they are causing issues. There shouldnt be engine bay heat issues.

Is your exhaust system stock? Make sure it does not touch the hydraulic line.....I doubt if the slave cylinder is the source of the problem.
