2001 with fuel problems

I have a 2001 blazer, which a year and a half ago had the fuel pump and filters replaced. The truck will start up perfectly, even after a cold night. If you run to store and start it ten minutes later it will start, but it acts like it is not getting fuel, and finally will kick in.

What engine?
Any check engine lights or codes?
Check fuel pressure when it does it and watch for fast leak down.
Post back fuel pressure readings and if any codes.

My truck was acting something like this and cleaning the mass airflow sensor fixed my issues. I would check fuel pressure first but cleaning the MAF is easy and free as well. I took mine apart and cleaned it very gently with some Q-tips and rubbing alcohol. I should add I was having some driveability issues like lack of power for the first few minutes of driving, like it was starving for fuel.
