Okay to answer this question for myself ( and anyone else who has this problem ) the resolution is N-Fold
Ctrl-F within the quicksave file to find your vessel
ForEach vessel v.currentThrottle c > 0 : set c = 0
set vessel v.mainThrottle = 0
Save file and perform a quick load and your vessel should have no active thrust on any engine.
This solution is offered as is and the provider bears no responsibility if your computer breaks escape velocity.
