Hello, My wife and I bought a 2005 Convertible about 4 weeks ago, the car started acting up about a week ago and we would attempt to start the car, power to all the lights and instruments but would not try to turn over. Wait a little and then the car would start. The battery was load tested and then replaced, same problem two days later. Tried disconnecting the two cables based upon a suggestion and then reconnecting them and the car still did the same thing. Started this afternoon drove it a short distance and the car did not start - several hours later it did start. Any suggestions?
