Why did my GTI just shut off all of a sudden and then after sitting for about an hour start right up like nothing was wrong. After running for about 20 do the same thing? Any ideas?? Thanks!!

If you have a Cat, the guts may have melted into a ball which rolls backwards under acceleration and blocks the exhaust.
If you have junk in your fuel tank, it gets pulled to the pick up and stops flow. settles out after a while ,then repeats. Or a clogged filter.
your fuel pump relay may be failing.

Sorry, my crystal ball does not seem to be picking up your GTI's malfunction.
More information please.
Did you check for spark?
Can you hear the fuel pump(s) run?
Describe the idle for us.

You guys kill me

Anyways, maybe this is your problem, maybe not.. but when my Rabbit was doing the same thing, I noticed that the gas cap was cracked and leaking. Replaced it, never had the problem again. Wierd, but worked.
Check the relay, pumps, etc after checking the above.
