The people jumping on the OP have probably never had this happen to them before. It's not a good feeling, especially if it happens twice. Getting stranded sucks and it makes it difficult to trust your car especially if it's due to something like an electrical gremlin.
I'd cut the guy some slack. It's very easy to get emotionally hot when you have to deal with a situation like this.
I hope the car gets fixed and you can get back to enjoying your Z without any more problems.
If only the forum as a whole could be more supportive instead of defensive.
