Mine is doing the same thing. Called my mechanic and he said the drop the blow and clean the low idle jet. Said a wire from a regular wire brush should work. Also told me not to run old gas through it or mix old and fresh gas and put some sea foam in it once a month. I just got my 03 so I'm still feeling my way around the bike and learning the ticks. Hope this helps, I'm going to try this fix today when I get off work. I'll let you know if it works.

There are 3 categories for failure. Mechanical, Electrical, and Fuel. Eliminating mechanical you can focus on the other two.
Electrical: Put in a fresh set of plugs properly gaped. If you're still running the stock plug wires replace them. Check the battery cables, clean / tighten.
Fuel: Replace the fuel filter. Ensure that the Air Filter is clean and properly attached. Run a couple tanks of Seafoam through the system. It's fantastic stuff but it may be time for a Carb overhaul.

If it's running then dies or won't restart, carb is the 1st place to look. Drain that tank, clean the filter, get those jets out of the carb and blow them out. Also, your petcock is vacuum operated, mine went bad years ago. Replaced it with a manual one.
