If it shuts off as if someone turned the ignition switch off?

Crankshaft Position Sensor.

Another idea, faulty ignition switch. Try driving with just a single key in the ignition, not on a chain of keys. If that helps the ignition switch is probably the culprit. Dangling keys can swing when going around corners and over bumps & eventually damage it.
