This sounds like a moisture problem. As Dave said, I'd suspect water in the 
gas tank if you drove it on wet pavement. In that case, check your overflow 
hose for cracks, as they will admit a lot of water which you may not even be 
aware of.  

If the car was not driven in the wet, then I's suspect wet ignition parts. Take a 
dry cloth or paper towel and simply dry off the dist cap and rotor, inside and 
out. Be careful of the spring loaded carbon brush inside the dist cap as you 
can break it off if you are careless with it. Dry off the nose of the coil. Inspect 
all these parts for spark tracks.   

I would also dry off the spark plug wires and connectors. If this doesn't seem 
to help, try looking at the engine in the dark while someone else is keeping it 
running. If it is really dark you may be able to see where your problem is.  

Note also that VW introduced some special silicone rubber covers for the SP 
connectors in around '70. These are EXCELLENT for preventing moisture 
problems at the SP insulators. If you don't have these covers they can still 
be purchased from your dealer. They are somewhat expensive, but worth it. 
They will also last forever if not abused.  

If your engine no longer has these, reach in and dry off each SP insulator, 

If you have opened up your SP gap above .028", or if the SPs are old and 
have rounded edges on the electrodes, they will require higher voltage to 
drive a spark across them. This means that everything else has to go to 
higher voltage, too, so there is an increased likelyhood that the spark will find 
an alternate path to ground, rather than fire across the plug. This will also 
give you more trouble in wet weather.
