I've been getting the very same problems on my FL S8. Just to add a bit more confusion into the mix; have you checked for air leaks. Since my problems started I have found a few air leaks in the induction system and have replaced the two rubber elbows on the air box and throttle body and now I feel I have air leaks in the manifold.
Like you I've changed my MAF and a few other things without any result.
One thing you can do which may help is to give your throttle body a good clean with some carb cleaner. Refit with a new gasket and see what happens. You may have to do a throttle body adaption afterwards but this is a simple process.
My problem doesn't happen that often now as I think I'm getting close to solving this once and for all but a trick I use when it does occur is this: stop the engine then turn the ignition back on without starting the engine and leave it for at least 30 seconds before turning the ignition off. Turn the ignition back on and start the car. During this process DO NOT TOUCH THE THROTTLE PEDAL or else it won't work. If this procedure works for you then it could indicate a problem with the throttle body.
Hope this helps.
Steve
