I had that with one launch, the throttle cable was full of grease and the entire run was so long the thing was taking the shortcut and compressing the Morse cable tube. Over about 15-20 seconds the cable sheath or tube was relaxing as the grease let go finally allowing the cable to move the injection pump rack arm... Took a long time to track that down.
