Falling Out of 3rd Gear on Track

Falling Out of 3rd Gear on Track
I have a new problem with the 5-speed gearbox in my '04 RS track day car. It "falls out" of 3rd gear fairly often on the track, when I am not hard on the gas. If going through a turn with a light amount of throttle, the gearshift lever just moves itself out of 3rd gear into neutral. This is very unnerving when I get on the gas exiting the turn, only to find out that I am not in gear.
This never happens on hard acceleration in 3rd gear. If WOT, or even 1/2 throttle, the lever stays in 3rd gear. And it never happens on the street.
The gearbox has been rebuilt once by HB Mitsu, probably almost a year ago. They replaced all the synchros, hubs, sleeves and 3rd gear. It has run a lot of HPDE track days since.
Any ideas?

Not that I'm glad to see you have tranny probs, but it confirms what I'm going through with my car. Mine is getting progressively worse and I'm pretty sure I don't drive it as hard as you. If I decide to keep my car I'm gonna have to get a Shep or TRE tranny. I haven't heard anything good about dealer rebuilds. I am guessing my stock clutch had a little to do with it also. I had the stock one checked out a few months ago and had a stiffer disk put in to see if it would help, but I think I'll need a whole new aftermarket clutch assembly too. Good luck.
