If you have went through 3 Optis in the last year, something is wrong.
Either crappy parts, bad install, or the problem is somewhere else.

When it is running, is it running good? If so, it probably isn't the Opti itself.

Still on my factory original Opti in my '96, with over 120k miles

Are you sure that you are loosing spark . When it cuts out turn the key on and listen for the fuel pump. If you don't here it, the fuel pump relay or pump may be the problem

See if there is a code for the opti. It would be 16.

How long does it shut down for?

You may need to measure the voltage for the ICM from the ECM for more data.
