Like I said these are all symptoms. What chain of events could cause them all to happen? What are the things that tell the ignition system when to fire? Crank position sensor? Cam position sensor? This is where you start.

Have a good Porsche mechanic look it over for you.
Thanks,
I didn't think about it that way. I am going to bring it to a porsche mechanic, probably save me a lot more time/trouble :dance:

Smart choice, replace only the part/parts that are causing the problem.

If it was a GM and parts are cheap as dirt then who cares but Porsche parts are too pricey for the shotgun approach, besides it is much more fun to actually figure out what it is doing.
