SOURCE: golf gti 2.0 8v keeps cutting out now it wont start
Just found your problem while looking for solutions to my own. My 2.0 8v 3door 97 golf gti can also cut out after driving for two or three minutes. Works fine one day then dies instantly 5 times the next...not a safe thing to happen pulling out of a junction!! Have researched problem and been told that it's probably fixable for £12-15. The "Hall Sender Relay" which is the fancy name for the ecu's power supply relay can go on the blink and cut power at any time causing instant shutdown...just like turning off the ignition key. Part number is 165906381 and available from a local vw dealer usually overnight. I'm fitting mine tomorrow 4/4/09...fingers crossed!
Hope this helps others...worth a try for the cost involved.

Some things you can check. First, with the engine off, look down into the carburetor and quickly move the throttle. You should see a squirt of fuel. If not, the accelerator pump is bad. If that is OK, check the spark itself. It should bridge a half inch gap with no problem and should be healthy (have good "snap" and bluish color). If OK, check the two wires that run from the ignition module inside the distributor, down under the breaker plate.Often those wires can partially break or short to the housing...when the advance moves the plate it will cause a problem.
Only other thing I can think of is timing. That engine likes from 8 to 12 degrees advance (depends on fuel quality) if it's set wrong it can make it fall on it's face when you floor it. (bad chain can do that too).
