My 1999 Suburban hiccuped a couple of times and quit running while driving 30-40 MPH. It started 1 time for about 10 seconds after I coasted to a stop. Would't start again. I changed the fuel filter. The fuel pump pumps a good stream of gas but it won't start. It turns over real good. Any ideas????? 135,000 miles no prior problems ever.

First you need to determine if you are missing spark or fuel.
You stated that the fuel pump will pump a good stream....you need to check the pressure...that truck needs about 60-65 psi to run.
Next I would check for spark, remove 1 plug wire from a plug and spin the engine over...do you hear and see spark jumping out of the boot?
