Sorry to hear about issue. A Porsche only shop is the only option. Dealer or Indy. One coil would be available. Do you want to check the coil yourself? People will sell you one. Sounds like can diagnose if both fuel and spark are present, compression, and leakdown DIY. Has it always had premium fuel? Plugs been replaced? Have you ran Techron (or similar) through it regularly?
