FYI: I'm new to 2-stroke bikes, so I'm just learning the in's and out's of the motors and such. So I do have quite a few questions. 
Just over a month ago I bought a barely used 2004 TXT Pro 300 (not even a single scuff on the bodywork). Anyway, yesterday I was in 6th gear going up a dirt road (gently sloped upward) and after about 1 mile of this the bike died. It basically sputtered and quit. Exhaust smelled a bit funky. Kicked it a few times, nothing. Waited 5 minutes and it fired right up.
I've never had a problem with the bike under normal trials-like conditions (the fan does come on fairly quickly when puttering around in 1st doing obstacles), and this was the first time I took the bike out and bombed up a road at such speed for the distance that I did. So my questions after this experience are:
Is what I experienced just 'normal' overheating?

For what it is worth, yours sounds just like mine...
You might have fixed this already with some other problem solve ideas given, but for what it is worth:
My 04 300 (early shipment) I think, had this same problem!
Well turned out that the {original???} Float Needle (which shuts off the fuel into the bowl) was made in 3 pieces, and was spring loaded inside the needle itself... instead of being just SOLID needle, which when they sent me the new one was solid. go figure?
When I finally figured this out, the needle was stretching in lenght due to vibrating? itself half apart... Man what a beyotch to figure out. I had that carb apart 100 times that day, bfore it finally reared its ugly problem part. that needle in mine, because everytime you looked at the needle and float level and at the needle itself, it all seemed to be fine. (this thing reared it's head in a day 1 of 2 day stranding me out on the loop just after the last section).
after having the carb off 100 times that afternoon/evening, as luck would have it, I almost dropped the float needle the last time. when it bounced onto the table, it "popped apart." finally exposing the fact that the 1/2 inch long needle was able to add 20% of its lenght to itself, when it wanted to, meaning fuel was shut off.
WIerd but now it makes sense,all them 3 loops I would tip the bike over (flooding it) to get it started... and it would run our short sections then be running like crap.
temporarily fix, I ended up smashing the keeper in the needle so it was solid needle for the rest of the trials, all was good.
As I reflected on this, when I found this issue, the bike would act lean after as little as 1/4 mile stint down the trail or so. I would of course usually shut it off walk something and ride slow most of the time (riding to and from my little area I ride at home and never much more than went "hmmm")
this thing seemed fine putting around in sections at the play area for months.
Anyway, after the new needle all this symptom is gone... Runs much coooler too!
