Resolve the issue by connecting a jumper battery at the starter.

I have always used the MSD by getting its power at the 3 fuse box in the engine compartment, without issues for over 10 years. Also, MSD datasheet says it will fire with as little as 7V, so I am not sure that will resolve the issue (but will try).
