ignition coil maybe.

Or a loose wire at the ignition switch, but normally if its that when you turn the key it wont do anything. But mine would do what your describing ONE of the times i had a bad switch

i replaced the ignition coil an it still does it

im thinking possibly fuel pump........if its on its way out i could be overheating and shutting down .......check the fuel pressure and wait till it stalls see if the pressure drops

Did you have this problem before the new opti or did you install this opti in an attempt to fix this problem?

The reason I ask is because I had a brand new opti do this to me. Once the car warmed up the optical sensor would stop working and the car would just shut off with no codes. If you have access to a scanner (I used a Snap-On MODUS) let the car run until it shuts off on it's own and then check for both high and low resolution signals while cranking. I replaced the optical sensor with one from a known good unit and the problem was solved (until the rotor exploded).

If this problem existed with the old opti as well as the new one then it's unlikely that this is the cause of your problem.

Good luck.
