Hi everyone: Bought my Tahoe brand new Jul 2007, on my firts trip 2008 hot summer 110F, climbing high mountains 15 miles from bottom to the top, and in the middle all of the sudden the car acted as it ran of fuel, engine quits. Fuel tank almost full, engine temp normal, restart it after couple of minuets, it started and after 1/4 of a mile it dies again. it took me 20 min to go up the mountain after several starting attempts. At the top I rested for 30 min and resume driving, everything is fine, engine started and drive smoth, all miant interval done on time and perfectly. It does this in climbing high hills and in hot days, second time this happend on summer 2009 and third time was 2 weeks ago, other than that my 2007 Tahoo runs perfect. Some told me it is the fuel pump, does that when it gets hot. I did not check the fuel press nor done any tests, I will do that soon, till then I wish you could guidr me to the probbable cause, and what is the cure. Thank you for the assist. Hamid.
