Whats interesting is that it is not a consistent issue correct? It has happened to me 3 times, all occuring between 70 - 101k miles. The first time was after a road trip to Florida. Car was low on gas (bout 1/4 tank). Stalled out while driving, just started hesitating, choking, then died. After letting it rest for aprox. 30 min. she was fine again. The most recent stall was the same situation but after a 18 hour road trip from MN. The car had NO issues for 9 months in the winter while we were in MN, then after an 18 hour road trip of perfect driving, 28 mpg, she stalls out in Atlanta traffic.
So I'm perplexed...our issues could be completely non-related, but what you experienced certainly was the same thing. Vapor lock I would think is not an issue due to the high pressure fuel pumps we have...
Let me know if you experience it again, I'm very curious. As for now...I think I'll have to run some tests before replacing any parts...do you know what your fuel trim measurements are?
