Had very similar symptoms earlier this year on my 2.6. Initially thought the crank sensor, but a replacement didn't cure it. Symptoms worsened, with intermittant cutting out whilst driving, then immediately firing again due to the engine still turning, until the dash lights started lighting up like a Christmas tree. Fault was diagnosed as a faulty engine ECU, and after a new replacement was fitted and programmed, the car has never run better.
