I'm getting it too with 246302 and some previous designs in the same family. Just now an order to orbit a star ended up with a sundive. I think the issue may be the AI not knowing what to do if it can't bleed off excess velocity in time. Very annoying, as it can be quite sporadic. I had a harvester working for a couple of days (at least 5 runs) before it decided to burn up in the gas giant it was supposed to harvest. Yet this latest sundive was the second within the span of two hours. Ah well, at least they're cheap and quick to build.
EDIT: On investigation, it seems the latest bout of diving is because of the lag. The AI pilot simply can't react as fast as it needs to.
