Finally got a chance to get back to you....thanks for your help, but after several tear downs and inspection of hoses, fuel pumps, carb etc, I pulled the fuel valve out of the gas tank......you wouldn't believe the amount of dirt on the intake filters for both the main and reserve lines.
I cleaned them up and it no longer stalls........now if I can just get it to stop backfiring when I let off the throttle.

you could have low antifreeze, faulty temp sensor causing the engine to kill itself (dont quote me on that, dont know if that year even had that option). check your radiator for pinholes. could be the camshaft problem, too. you could have a bad oil injector too.

Hey Younger did you get you problems sorted out?
I picked up a 2000 scrambler 500, sounds like I am having the similar problems
QUAD always starts and runs great for about 1/2 hr then it seems to starve for gas
a bit of sputting and dead. usually takes 1/2 hr to an 1 and boom quad starts up right away
Is this similar to your problem? let me know how you made out, if it's fix?

Darren,
The "stalling when hot problem" was fixed by pulling the fuel tank off the bike. I removed and cleaned the fuel valve.....could not believe the amount of dirt I found in the tank collected on the mesh of the fuel valve.
Have you checked the fuel lines yet?

You could tell him to weld up that weep hole also since you already gave so much more BS info

Hey Younger, yes I pulled the tank off, pulled and clean the fuel valve,
and blew all the gas and air lines out, guess we see,
My shutting down was accuring after about 1/2-45min rides,
Have not taken it out that long yet, hopefully this is the fix.
guess I'll tackel the sensor's if not(thx cornbread)
