Mine just started doing this too. Could it be a slow leak in the trans causing it to leak fluid and mess up the syncros? I have a new trans on the way from the shop that I'm putting the retrofit into so I can inspect this one after I pull it. I'll probably check the fluid level this weekend. It's been running strong for 15k miles and I don't know how many miles it had on it before that.
