Could be a pin hole warn in the delivery line(pressure) inside the tank.
Maybe it's time to replace it and the fuel filter, about $100 for parts on my '07,did it at 25000 mi.

Removed fuel pump assembly. Checked the soda straw looking tube that comes off the regulator and it had a leak, Aha! When fuel level got to the leak in the hose it would lose pressure. I replaced check valve/hose and gas filter while I was there. Test drove all was good till prob#2 decided to finally cause lose of voltage problem, but I didn't have my meter hooked up. Waited about 90 seconds and voltage returned and it cranked up and off I went. One down, one to go. I am pretty convinced I have a failing circuit breaker but want to prove it so went its fixed it's fixed. Thanks eleft, I just read your post after repairing exactly what you suggested. You ROCK!

 

Did you replace the line with oem or submersible fuel hose?

 

OEM. It comes with the quick connect valve already attached. Thought about just putting a hose on the old valve, but was only 40 bucks and I probably wouldn't have replaced the filter if I hadn't talked to parts guy. Damn filter was $60
