I don't think it's the fuel pump as it was fine over the previous week when temps were below tripple digits, as well as for an errand I ran in the morning when it was only 85 or so.
The fact that the fuel pump was OK the previous week has no bearing on it's performance this week. If you haven't tested it, you don't know if it's working.
Stuff has to break at some point. Just ask the guy who keeled over from a heart attack, thinking "huh! my ticker was fine just a bit ago."
