Answers :

I had this same problem with my 2003 H2, my mechanic found that the fuel diaphragm was cracked and this was allowing my truck to flood. If it was a cold start, the extra fuel would evaporate and it would start fine. It actually got to the point where I would stall at a stop light or stop sign at idle. The part was is the neighborhood of $175.00 and about 1 hour of labor to install.
