Have the fuel pressure tested with a mechanical gauge.
Have the coil tested.
Another posibibility is the ign. Switch. If, when the car cuts off, the wipers or radio also do not work, then the ign switch is bad.
If the above is OK, then I would check all fuses and fusible links, inspect all wiring for any open insulation or burn marks.
But the fact that the tach. Is acting erratic leads me to believe it is ignition.
