This is a distributorless ignition system, with MPI fuel system. Sometimes runs for a a minute or so, sometimes just a few seconds. Dies abruptly with no sputtering. Scanner reads no error codes. Have visually inspected everything I can think of. Fuel pressure is within specs. Fuel regulator is working. Battery cables and connections at battery clean. When engine dies, dash lights come on. I'm at the end of my rope. Any suggestions would be GREATLY appreciated.

Put a fuel pressure gauge on the shrader valve and see what the fuel pressure does when, or right before, the engine dies.
Double check that all the wiring connections on the coil, crankshaft sensor, ECM, etc, are properly seated and locked in place with their little plastic clip.
