Same problem here.
I have a 2003 Dodge Ram with a 5.7 Hemi. the other day i was driving and it started to tremble and finally it stalled. Now when I try to start it sputters and and stalls. I was thinking maybe my Fuel Pump , what do you guys think?

Same prob: 5.7 misfire/sputter/stall
Hi, I am having this same problem. Have someone coming in the morning to try and diagnose. Will keep the forum informed. Has anyone found resolution to this problem yet? Seems to be common
today when i started my 2003 dodge ram 5.7 hemi it start fine and run like normally for 30mins then when i was driving down the highway the Engine started to tremble during driving & loss of acceleration power....if i press the gas peddle straight down the engine strugles & pulls off but with the force it trembles alot...like it's straining to move and the engine light flicked on for a couple of seconds then went out, when the truck was put into 2nd gear it seamed to run better, on my way home it got worse and now when i start the truck you have to give it some gas and it will not stay running, so i stop of at the dealership they said they think its the injectors. i am not sure if it is that because i have never had this problem before with the truck i think its kinda of rare for all the injectors to go at once. also at idle in neautal you have to hold the rpm to around 3000 it will not run at anythink less.
P.S. could this be a valve spring

Update
Well, only code today was engine collar check.... low on coolant so that was a given. Removed air box, intake is dirty inside like it was spitting back out. Spark plugs wet n gassy. Cleaned PCM connections. There's a "clicking" when it's trying to idle, really rough coming from driver side, front engine. Thinking timing may be thrown off..... does this sound like something that would make all this misfire and sputter? Thinking to start there and then move on to valve seats.. someone mentioned they may drop/break. Used digital scope to look inside cylinder and seemed clean.... any ideas on all that mess? Thanks in advance for any help
