I have a Holden Barlina 2004 VY model v6
I have it for at least 2 years now, but this issue only started to happen two months ago.
As I turn it on, it goes smooth and quietly, but as I drive, approximately 5 to 7 minutes down the road, when the RPM is down, it would then shuts off without notice, or even when I accelerate when lights turn green, it shuts off midway.
NOTED: this only happens during early morning or at night when it's cold, and once it did that, it would not happen again during the ride. According to one of a mechanic, he claimed that it might be an electrical problem.
My question is How likely that it is an electrical problem? if it's not What else could it be and what could I do to resolve it?
