here's one possibility: from Technical Newsletter, 88-N04 ........................................................................ Volkswagen Technical Newsletter 88-N04

High Pressure, Low Performance

A Volkswagen that stalls when the engine is cold or after driving a few hundred feet could be suffering from an air/fuel imbalance. It could also have a bad oil pump. That's right, oil pump! If the same engine has zero compression, the chances are even greater than the oil pump is to blame.

If the oil pressure relief valve sticks, oil pressure could rise to over 200 psi when you accelerate to drive off. With pressure that high, the hydraulic valve lifters will overextend themselves, causing the valves to hang open. After the engine warms up, the car will probably run great the rest of the day. So check the oil pressure when you've tried everything else to solve a stalling problem ... believe it or not!
