1998 Volkswagen Jetta NO SPARK TO ENGINE

Engine Mechanical problem
1998 Volkswagen Jetta 4 cyl Front Wheel Drive Automatic

The car just cut off after drving it to the mall. My mechanic checked the coil, the wires, and the 3/6 pins and the timing belt and they are all good. Please tell me what this could be. I need this for my second car. I have tried everything even the mechanic is stumped he said this is the 2nd car he has had that has had this problem and he could not figure it out.
