LR have screened the cable from the sensor to the ecu for a reason. I am still convinced it electrical but I may be wrong. Its difficult at the moment as it an intermittent fault, so I am trying to re-create it so I can get some testing done. I always find doing diagnostics better than just throwing parts at it. Fortunately I have access to a second vehicle so I am in position to do this.
Generally speaking the ones I've seen that had unusually "noisy" starter motors that caused very poor starting, would indeed start in a similar fashion to what you speak of, but would not be as exactly repeatable as you have described, they also throw a "noisy crank signal" error, so you should have seen that if it was an issue.
