Made it to Myrtle Beach, barely...

I do not recommend ST class tires on anything used out on the freeway,
but going two classes higher to 'LT' class requires possible changing
the wheels to handle the higher PSI's. But they should last longer and
IMHO, safer than ST class

Agree, most likely the Sub's fuel pump going. How often has the fuel
filter been changed? That is the main culprit in killing this era fuel
pump.

In a pinch after the fuel pump stops...is to wack the bottom of the fuel
tank while someone is cranking the engine. It 'might' start and DO NOT
turn off the engine...this is generally a one time thing...

The fuel pump in inside the tank and the tank has to be dropped to change
it. Done that twice and no fun...third time had it towed to the mechanic.
Get bad gas every once in a while and is typically out in the boonies and
know the sound of the fuel pump going...makes more noise and a
different noise...learn how a good pump sounds like after or if that
is the problem

I do change the fuel filter often, about every 1,000 gallons fuel, and
carry extra filter & flare nut wrenches in my Sub's toolbox

I don't go over 60 on the interstate. I know ST aren't the greatest, but was surprised at this.

So far I've been able to get it going afterwards each time, and it works fine. Haven't noticed any difference in the noises under the truck. About 1000 miles ago I had it out to replace the seal between the pump and the tank. That wasn't an easy job for the mechanic for sure. I'm not even sure I wan't to know what the dealer is gonna charge for that.

I can't do anything really today since most everyone is closed on Sunday here. There's an Advance Auto Parts outside the campground I may run to later to see if I can get a code read done.
