Hi Johnny,
I use extended temperature range micros in my equipment, mainly to get the low operating temperature down to -40C, but that only gives me a Tjunction of 125C on the high end. I'm thinking when you shut down to fuel up, the Tambient on top of the engine is going to be up in that range, or maybe more. Upon startup the Tjunction going way above that. I know there are aerospace/military devices with high junction ratings, but they come at high cost... let alone other components like capacitors that don't like heat.

anyway, its a concern and the poster didn't want to get into a slamming contest, so I'll leave it at that.
