Disco Mike may be on to something. Last summer the truck died a couple times. The condition would only occur with 1/4 tank or less and hot OAT. Allowed to cool and back down the road. Thought it was a coilpack, spyder....nope just replaced the filter (first time) and seemed fine.
I just replaced a fuel pump in my Suburban w/75k and am trying to convince myself that is not it! That was not fun with about 40 gal gas in tank.
If I hold out for the 3.5 hr (80MPH) journey to the dealer I might have the Recall for the tank performed. I wonder if they will give me a break on labor for the pump replacement? Or am I dreamin again!

They should give you a break, they SHOULD NOT charge any extra labor. The only charge should be for the pump. They're job will be easier as they won't have to carefully take out your old fuel pump to use again. All they have to do is slap the new one in.

The fuel pumps are a dream to replace. There is an access hatch in the trunk. Just pull back the carpet, remove the cover and bang, there it is...

no need to drop the gas tank.
When you have the gas tank replaced if you have a large vent line (5/8' x 2') have it replaced also.
It is on top and you have to drop the tank to replace it.

Hey Spike, the thing finally died ironically on Christmass. Had all the kids dressed up and loaded in the Suburban on the way to church, would not turn over (ended up being a ground I bumped putting the back seat back in)... So loaded up the explorer and rover to accomodate seating and ....rover wont start either!! This was like something out of one of those holiday comedies except my wife was far from laughing.
I decided to try the crank sensor first, as it was cheap and easy to access. (should have done a little more investigating but had a bad code once a couple months prior and just assumed). I do hear some reventing back in the tank like fuel is squirting back in the tank under pressure. Sounds like I will try a pump next. Have good spark, and occasionally hits a couple cylinders but wont really start.

Most fuel pumps have check valves. When fuel is pumped into the lines, this check valve keeps the fuel from bleeding backward out of the fuel lines and back into the fuel tank. Without this feature, the fuel system wouldn't be able to hold sufficient fuel pressure. This would make engine startup difficult especially after the vehicle has been sitting for a reasonable amount of time.
Either that or maybe a fuel pressure regulator may be your problem.
