So I ran into this a few months ago and very appreciative for everyone's help. My car died on the road and after troubleshooting all electrical, I ended up replacing my fuel pump, primed the lines, and she started right up. I drove around 300 miles and everything was fine. Last night, I went out for a little ride and as I'm pulling back into my neighborhood, the engine shuts off and will not restart. I pushed it back to my garage. This morning, I turn the key and it fires right up. Any ideas?
