I was riding for about an hour when my '03 GTI lost power & shut down completely. It would restart & then go again for approx. 5-10 seconds or so then do the same & shut down. It would idle fine, but whenever giving gas it shut down. Never had any issues in past couple years with it, new battery this year & new gas. Seems like it is getting choked out, any ideas?

hey....start with normal routine,...compression, go thru fuel system...etc..:cheers:
Do a compression test first to see what's going on inside first.Than clean the carbs if the compression is ok. Here is some information;
You'll need a compression tester. Go to Auto Zone. I think they sell for like $25.00. The compression gage, will screw in the cylinder head in place of the spark plugs. To test compression, remove both spark plugs. Place spark plug caps on the plug cap studs near the cylinder head to ground the empty caps. This completes the circuit of the ignition electrical system and prevents any electrical problems from the caps being un grounded. Using the correct adapter for the threaded end of the tester,( same length of the spark plug threads length)screw in the tester in one plug hole. Hold the throttle wide open. Push the start button. Watch the compression gauge, when it peaks out at the most compression, let go the start button. Read the psi number. I would do it 3 times to be sure it is accurate. Check both cylinders the same way. The ideal compression is 150 psi per cylinder. If it is less, it's not a problem as long as they are close to being the same. If the psi is less than 90 it might need be time for a tear down and a rebuild. If the psi in 1 cylinder is say 140 psi and the other is 80 psi you need to tear down and repair. This difference is a lot and there is a problem.
It sounds like you need to remove the carburetors and clean them. If you're careful and don't tear or damage the diaphragms you won't need to buy a rebuild kit. Pay attention to the internal filters too.
I hope this info helps you out.
