High Elevation Misfiring

High Elevation Misfiring
2002 XKR
On a recent trip requiring steep inclines to high elevations the vehicle experienced first misfires then the engine would shut down completely.
Upon restart all functioned smoothly until another steep incline caused the same result. Vehicle ran fine at high elevation and all the way back down to sea level. Diagnostics were run at my Indy with no result.
Anyone experience the same?

I've been told that the computer checks the barometric pressure and adjusts the fuel accordingly, but only when the engine is first started. As you change altitudes the computer can only adjust within a narrow range, therefore the engine will run rich. Hence, when you restart the engine everything works good.
