This seems the most likely to me, I suppose... perhaps there's a time-limit on how long the heat shield can last once it begins to heat up a little?

And because cooling in space is difficult. There's no air to conductively or convectively cool the heat shield in between passes. There's only radiative heat transfer and that isn't very effective in comparison. The heat shield would bake. This was a factor if you used my old re-entry heat mod (long since retired). I don't know if the current deadly re-entry mods model this effect.

IRRC they obliteratively (spell?) cool the heat shield at times. It burns/breaks off taking the heat with it. :P
