Intermittent Brake Failure

I was presented this evening with a 986 which may have an IMS failure, but this new customer came to me because she had 'broken up' (her words) with her last Porsche mechanic over a brake issue on the same car.

Apparently it's happened twice. The pedal goes to the floor, she swerves to miss traffic, uses the parking brake to stop and then, after a few minutes, the brakes return to normal.

The master cylinder was replaced before it happened a second time. The two events were weeks apart and the computer can find no faults or stored codes in the ABS computer.

Anyone seen this?
