Here's my situation:
1. I filled-up the Escalade. That's 26 gallons of fuel.
2. I drove the thing 209 miles on straight and level Interstate 40 (between Little Rock, AR and Memphis, TN)
3. Without warning the engine lost power. DTC came up indicating "bank 1 too lean, bank 2 too lean". Obviously, that meant there was no fuel getting to the engine.
4. The fuel gauge read just under 1/2 tank. After turning off/on several times, it read the same thing.
5. Turning the key ON, I could hear a brief whine from the area of the fuel tank. Pretty sure it was the fuel pump not getting gas.
6. If I let it sit for a few mins, the truck would start up, but after about a minute, I would hear that whine again from the area of the gas tank and the engine would sputter and die.
7. I had AAA deliver 3 gallons of gas. I then was able to drive the Escalade as normal to a gas station a few miles away and fill it up. I then drove it home with no further issues, which was an additional 86 miles.
I filled it up, and this happened after 209 miles. When I gassed-up, it took about 13 gallons. Add the 3 gallons AAA sold me, that makes 16 gallons. That means I had 10 gallons still in the tank; the fuel gauge was accurate.
This has happened a couple of times before; loss of power but no further problems after gassing-up.
Does anyone have any ideas about what's going on? There's several gallons still in the tank yet the engine isn't getting the fuel. Other times, I can run the thing down to near E with no problem. Yes, I know it's not a good idea to run it very low or dry.
I don't know how the fuel pump is arranged to receive the fuel, but it's almost as if it siphons from the top and it's not reaching down to the bottom of the tank.
