According to the original post, this has happened twice. Out of how many? Twice out of 20 hot starts, 2 out of two? Anyway, I think the two most logical answers are poor ground or starter getting tired. Running a ground strap should be SOP anyway, so I'd get that done then keep an eye on it. It may also be a good idea to use the crank a few times to get a feel for how the engine turns over hot, then when the problem happens again try turning over by crank and see if the engine feels tighter or not.
