I was thinking about this last night after I posted and remembered that the clock on my radio reset itself, during one of the shutdowns yesterday, but didn't clear the pre programed stations. So it seems to me that there was a power interuption to some parts of the system like a circuit breaker might have tripped and reset itself. Course I don't know if this car has circuit breakers.
I had a new key cut and didn't have any problems starting until this week. It'* been hot here in SC, high 80s low 90s during the day, and I'm wondering if the heat is contributing to the problem.
I cleaned the battery terminals several weeks ago even though they showed no signs of corrosion. Battery is only a year old also.
Thanks for all the ideas so far and hopefully someone will have had the same problems and will liet us all learn something new about this car.
