anyone with a 4 spd ever have this problem???

[knsmodels]

I have a K10 (dont think it matters 4X4 or 2wd) with a 4spd.....while driving the other day got a little to aggresive on the shift from 2-3 (or 1st to second depending on how you look at it ) and boom the truck would not shift into any gear.....shifter would go left to right and right to left but would not go up or down to get into any gear..(was stuck in neutral).....played with it for 20 min. before giving up and towing it home.......here is the strange part....next morning go out to truck and it is fine.....shifts like nothing happened.....just curious if anyone has ever had this happen and if it means something internally (fork??) is worn out in the tranny....maybe a gear hung up and did not totally disengage before the fork came out thus not letting me into any other gear????.......Thanks.....
