ROUGH STARTS H2??HELP!!!

[splne1]

It all started with a trip from Virginia to Texas last week. The drive to Tx was great no problems for the most part. I did feel that the throttle would open pretty wide when on cruise control going up hills and showing above 3500 rpm. Decided to just use my foot and it wasn't to bad. Anyhow it was the day before I was ready to come back that I noticed when I started it she gasped for air and then started, no rough idle or nothing??? Brushed that off and all was well. Again later that day same thing went to start and heard the gasp of air before the start. So now I am really confused , no check engine light, no rough idle, so I didn't think it was the fuel system. Checked the MAF sensor, nope clean as a whistle. So I am on the way home with this situation and as I cross the state line into virginia the real trouble starts. Now its not gasping for air its literally starving for it upon start. Cruising under 40MPH starts to bounce the the RPM slightly and you can feel it trying to keep running. Not excessive but I notice it barely completely sitting still at a redlight. I think I may have put some bad gas some where on the way back so I just tanked her with premium and threw some Fuel system cleaner and am hoping for the best. So far I did notice a slight accel improvement. Could it mean my injectors were dirty or what????? I am shooting for the worst and planning on getting a new fuel pump? Anyone know the PN# for the fuel pump?? Injectors??? Any help is greatly appreciated, and if in the VA area maybe a couple of cold ones for the help with this issue.
