Porsche 968, 1995 convertable:
The car is perfect condition, bought new and housed in garage. However, on random occassions car will not start. Starts fine first time, but after some stops when the engine is turned off, it is hard to start. The battery and started sound fine. On occasion it will start with portable charger, even thogh battery is getting charge.
One time started after 1/2 hour by flooring gas pedal.
Very random and non seasonal.
