Saw your note. Often times when the engine just died after 15 minutes, it's the ignition control module (ICM). The ICM IS located on the front of the passenger side cylinder head near the coil. When the car dies, a quick check is to pull a plug wire, have someone crank the engine, and look for spark. FWIW...pretty unusual for the ECM to go bad although it'll happen on occasion. I'd check the ICM first.

Roger - lets see some PICS!

Thanks Frank!

I did see Charlie at the Corvette show. I told him I saw you dropping off your C4 at his shop. Nothing more was discussed about you or your car's. Frank
