91' GL vanagon had the water pump replaced recently at the dealer place.
After the installation, the car now experiences sudden loss of power while
driving - engine suddenly lost power disregarding how hard I was pushing the gas
peddle.  I waited for a few second, restated the engine, ran for a few yards with
very little power, then died again.  I ended up towing the car back to house
- checked the timing, looks OK.

Could the installation of water pump (poor workmanship) cause the car loosing
power, temperature sensor, thermostat, etc.  Would appreciate your input.
