Since you don't hear the pump kick on then I'd start with checking the fuel pressure of your system. Autozone will lend you one for free. Hook it up and turn the key to on (past ACC but no need to...

Just to update things. I replaced the pump (filter and sender also) and it works perfectly even with the outside temp at 95F. I've driven it everywhere and can't get it to stall.
Thanks for the...

So, the excess fuel is super-heated (somehow?) and then...

I just found out it had the fuel pump and filter replaced in 2009. Not very much usage on the truck since then.

So I'm now thinking ICM or fuel pump relay??

Any suggestions?
