Help needed please 2003 tahoe 4.8

hey guys,

I don't know where to start: bachelor party in Vegas last weekend, layed off tuesday, car wouldnt start yesterday!! life changed really quick.

Went to start my car and it cranked right over but wouldn't start. Sat all night and i had 14volts, no flickering lights, strong crank. Raining so I couldn't hear the fuel pump or relay click but this is my initial thought.

after 4 tries it fired up and seemed fine. 20 min of highway driving and im on the gas at 65 and i feel the petal go weak and i cant give it gas for a second or two. quick panic and then i had gas again. its did this twice to the store and three times coming back.

on the way home i was coming through me neighborhood low speeds and this time after it cut out I could her a hum from my engine compartment. dash lights off, battery light on, had to turn the key in the ignition to get it started this time.

fuel relay
fuel pump
ign switch
crank sensor
anything else?


Im thinking its a fuel issue but wanted to see what you thought. I really appreciate any help of thoughts you might have.
