I'd go back to Planet. Make a note of all the data when cold then again when hot.

Sounds like the problem is the slow rotation by the starter when hot, presumably if it did this with the old starter, starter can't be the problem. Mystery, starters normally struggle when the engine is cold, might be worth checking the gearbox to engine earth strap connections and the battery to body earth underneath the drivers feet, just loosen them slightly and re-tighten so you don't disconnect the battery.

Further thought, worth trying to turn the engine with a spanner on pulley when hot just to confirm something in the engine hasn't tightened up.
