Hi Terry !
You do not need to change anything there. FS opens with engines running by default. If you made a flight with engines shutted down, and sqaaved it (overwrote) as default flight, your engines will be shutted down always.
Sometimes, it can happen when you switch to a totally different plane than before. Like switching from jets to small and weak propeller planes can cause an engine shutdown at load. Also it can be a factor of the panel you use: some panels can initiate a shutdown while loaded.
Cheer up
