Problem Description and Possible Solution
The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

Vehicle acted like it was running out of fuel and would stall out. Eventually, would not start. Waited for a period of time (temp to warm up in garage?) and it would start. Technician suggested hitting the fuel tank with a a mallet the next time it wouldn't start. Each time I did this, it would fire right up. Replaced the fuel pump and resolved the problem. Unfortunately, pump and filter are both in the tank, so more work/more cost to replace.
Occasionally lopes when at highway speeds. Gas gauge constantly shows empty irregardless of true amount of fuel. After driving for a few blocks, stopping and restarting will usually reset the gauge to work correctly. I am taking this as a precaution to replace the fuel pump prior to any failure that may happen in near future. This is one more annoyance that undermines my confidence that this Tahoe is reliable.
Fuel pump was going bad and engine would fail to start at random times. This left me stranded several times. If the engine will start and immediately run out of fuel in 1 to 2 seconds, rest assured it is the fuel pump which is in the fuel tank. So have it fixed now. The $400 or so isn't worth being stranded.
