timing jump

while bouncing through some fairly lump seas today the engine stopped, not to go again. when turning it over sounded like no compression and blew back.after a tow home we checked the timing and its a about a 40* out which is massive the engine had run faultlessy till the clocking some best ever speeds. im checking the timming tomorrow and pullling fly wheel but ant ideas. the internals all seem fine and connected. the splines in the crank are fine .

Not familiar with efi motors, so a bit of a stab in the dark, but if it still has the pair of switchpacks on the stbd side, is the idle speed module that connects to the switchpacks fitted? This adjusts the idle speed by moving the timing - if it's failed, or if a wire has failed or grounded, who knows where the timing could end up.

P.S. If so, you can safely disconnect it to try.
