Lost power all of a sudden. 273 commando.

This is also what I was thinking, maybe the arm on the shaft coming out of the trans slipped?

No, checked all linkages. It's fine, I had my friend press the pedal and the kickdown is also adjusted and set up as it should and as it was before when it was running strong. I'm thinking it could be a timing issue and maybe the Pertronix is giving up, as mentioned earlier. Will continue to diagnose when my friend have time to help me so I can properly check at what rpm I have full advance.
