Well, if you someday wind up in a ditch with the bike on your leg and gasoline soaking your pants...

Gasoline is not warm, brown and lumpy, is it?

Nope, that's adrenaline.

Has someone mentioned a clogged vent valve in the fuel cap? I think this is what GregP was trying to get at. If you have yet to resolve, loosen your fuel cap and see if the stalling stills happens.
The valve in the fuel cap that can get clogged. Vacuum builds up in the tank then and the bike starves for fuel. If this is the culprit, you need to take the cap apart and clean it.

Yes, that is what I was trying to suggest. I have owned many motorcycles and you would be surprised how many times I have come across clogged cap vents. The last one was on an '85 Honda Interceptor. The one before that was on a Craftsman lawn tractor. There are many different designs of fuel tank cap vents. Some just have plastic or steel baffles, some have a ball type check valve, and the Interceptor had a small plastic diaphram. I have not had any trouble with the cap vent on my T-3C, so I am unfamiliar with its design. You can get most caps apart to some degree, and remedy the clogged vent, but every once in a while I end up removing parts altogether and leaving them out, or passing a drill bit through the cap it some convenient area. As long as fuel does not splash out on to the tank, and it can breath, all is good.

Also a classic failure on the early 885 triple bikes.

I had the same bike, same year, and had the same problem.
To test the vacuum problem, when the bike starts to die, simply twist open the cap to release the vacuum, if the bike continues to die it is not a vacuum problem.
On my bike with the same symptoms, when the bike would reach temperature it would begin to slowly die, sputtering until it stalled. in 5 minutes the bike would cool down enough and start up perfectly and the cycle would continue.
my problem was with the ignition pickup, a 10 minute job to replace, and the bike runs perfectly.
unfortunately there is no test I know of to test the ignition pickup, but replacing it fixed my problem.
hope that helps

A friend of mines bike packed up this week, same issue, was told fuel problem he thought not and called a friendly mechanic who suggested ignition pickup (as walshja is suggesting) as Triumphs are prone with this.

Yep, ignition pickups do fail, but the fuel vent valves clog easier (and the fix is way cheaper). An ignition pickup is USD $80 from the dealer.
Any update on the condition, Schilzy?

Thanks for posting everyone..I really appreciate it. . Last summer I loosened the fuel cap as I was riding...thinking that it could be a vacuum issue. It didn't work. I'm wondering ...if it it's a fuel vent valve why that valve doesn't affect the performance when the shut off valve is on the reserve position? Forgive my ignorance, but the ignition pick up is that tied into staring the bike? The bike starts up fine on both the reserve and main tank settings on the shut off valve. It starts to act up after the bike is warmed up...usually about 15 to 25 minutes into the ride only on the main setting on the shut off valve.
