If you still have the problem - when its hot and wont start, pull a plug wire off one of the spark plugs, put an old spark plug into it, and let it lie on anything on the engine made of metal. Have someone crank the car, and see if there is a nice blue spark jumping the plug gap.
If there is, its likely a fuel problem.

i ahd the same problem on my 91 jetta gl. the problem is the coolant temperature sensor. cheap 10 dollar part. change it and your issue will go away
