Found that I need to do lock/unlock sequence after a pcm flash so that engine remains running after re-start.
Yup, gave myself the placebo affect there, couple of early starts after flashes were a bit weird, tried the unlock/lock and appeared to work.
So, now just flash in tune and all is good.
Making some good progress with help from behold, I'm up and driving on the road now with EFIlive doing the work !!!!.......
