Whilst driving home in 119* heat and a mile away from my garage the engine quit. We coasted to a safe area and tried a number of times to re-start but she wouldn't ignite. After battling with an overwhelmed Roadside Assistance for two hours, I returned to see if it would start and sure enough fired up immediately. I guessed maybe the fuel pumps might have overheated...The wagon has 250,000 miles and I do not remember any fuel problems ever.
Well it went for about a half a mile before shutting down again. So I walked home and will try again in the morning. Any other guesses as to what else might cause a situation like this?

I thank you for your answers in advance! And no I'm not moving to Alaska!
