hard to start on 2001 Chevrolet Suburban 1500

After driving awhile, it takes 2 or 3 tries to start back up. Why?

If a vehicle has a hard time starting when the engine is hot, this is often due to a problem with the fuel pump and/or the fuel system. The system is supposed to hold fuel pressure after the engine is turned off, if it doesn't it will be hard to start. Have the fuel pressure checked and make sure they check the rest pressure too.
