1999 Chrysler Concorde, engine quits while driving without indication

1999 Chrysler Concorde, 3.5L engine quits while driving. The vehicle is well maintained and has 133,000 miles on it. No check engine light when it fails. Will not restart after stalling. The engine just cranks and does NOT sputter. After it gets towed, and the first time an attempt to start the car, it starts right up. Oil is changed every 3,000 miles. Chrysler and other shops praised the shape the car is in. I'm the original owner.
