Assuming you have the ZF 5 speed, a common reoccurring problem is the throwout bearing collar binding on the input shaft bearing retainer that it slides back and forth on due to a gummy crud buildup. Ford came out with collar with a wiper on it to prevent the problem. Only other option, if that IS your problem, is remove the slave cylinder, rubber boot, and snake a vacuum hose in there connected to an oil squirt can and lube the retainer with a small amount of oil. It's a royal pain in the butt, but better than pulling the trans and all. I've had to do that every few years when I was using my truck 100% of the time.
