1998 Rodeo, 3.2, 2wd, 5 speed, 102210 miles, slave cylinder and clutch fluid changed and bled two weeks ago

so i went ahead and changed the slave cylinder and bleed via vacuum. things seemed better after first test drive. later that day, i went to the grocery store and when shifting from first to second the clutch stayed on the floor and the clutch slammed engaged. i limped to a parking lot, went and got my tools and removed the slave to find the push rod had fallen out of the cup on the fork. i just put it back thinking maybe i did not stab it right the first time. drove fine for two weeks.

same thing happened again at the busiest intersection on my way home today. this time it happened when pulling away in first. i left in first and started to get out of the intersection. same thing, push rod out of the cup.

could this be the throw out bearing hanging up when i let the clutch out? this would allow the push rod to fall out of the cup. then when the throw out bearing frees up, it would slam the clutch engaged with the rod dangling and clutch stuck on the floor. any other ideas?
