Thanks to all. Just thought I would add the fix.

The ground was fine, I have double checked them both and all is good.
The voltage on the battery at rest was 12.5v.
With the key out and red battery disconnected, there as 0 amps flowing from the battery + terminal to the cable cable.
With a battery load test, the battery read 1.5v.
When I boosted the car and disconnected the boosting battery, the car stalled.
When I boosted the car and left the battery on the load test on the charging circuit fell bellow acceptable but I would expect that with a bad battery.
The battery is a BMW original about 1.5 years old.
I replaced the battery with a Napa Battery ( 6 year warranty vs BMW's 1 year warranty).
All is well since battery was replaced.

Cheers
