There is a good chance that it's the fuel pressure regulator leaking over night and causing fuel to pool in your intake. This would cause your hard start in the morning, you can check but noting your fuel pressure with the fuel system primed. Tune the ignition key to the off position and see if there is any signs of fuel pressure lost within the next 5 min, if there is a fast reading of fuel pressure lost. You have a leak in your fuel pressure regulator.

The other area that could also cause this issue is a faulty CSFI system, here is a link that explain in full the issues your 5.7 vortec engine has concerning your SCFI system. http://members.shaw.ca/betterthanyoutoo/Sticking Poppet.htm

Keep me posted, be glad to help you get your Suburban running 100%. But start with the simple and replace your fuel filter, it's located in the inner side if your frame under the drivers door.
