We have been doing some work on the 99 SS and after it sits for a little while(couple weeks) when you first crank it it runs fine, but when you start to head up the driveway it feels like it is missing with no power. Above around 2500-3000 it clears up and after 20-30 seconds it is gone completely. It is not a DD so it does sit weeks at a time sometimes. Any idea on what this can be? It did it yesterday and threw the SES and I have not checked it yet. Usually it does not throw a code.

Oh yea......it Does not do it all the time.


Thanks
