I have a 2001 chevy suburban one day while driving the check engine light came on and the fuel gauge droped to emty the truck felt like it was going to die. I pulled it over turned it off check around the vehical got back in and started it up. When I let that location I felt a vibration in the front end through the steering wheel and seats. This only happens when I am accelerating. I can put the truck in nuteral and rev up the engine while driving and it drive nice and smooth but as soon as I put any pressure on the gass pedal I can feel the vibration again. I had the code checked and there is none. Nothing is lose in the front end. What could it be?

Could be a failing fuel pump that isn't giving enough fuel pressure to supply the engine under loads. You can check this with a pressure gauge.

Fuel pressure should be 55-62 psi and hold steady. (No more than 5psi drop) Check regulator by running engine and pulling vacuum hose. Pressure should increase. If not, bad FPR. Also check for presence of fuel in line. Any, bad FPR
