SAVANNA

2004 GMC Other

I have a 2004 Savanna with a 350 engine. 42,000 miles
For the last two months whenever I fill-up with gas, and to to start the engine it stalls out immediatly after a quick start. Upon a restart it runs great and no problems until the next gas fill-up and it does the same thing - everytime.
Now the check engine light comes on and stays on.
The book says it is something to do with emissions.
What is wrong with the engine?
Thanks.
