94 Dodge Ram 1500 5.9L problems?

Okay so this morning it was running fine, stopped a got alittle bit of gas, and then parked in my drive way on an incline. So went to start it less than two hours later and it wont stay running now. When it starts it runs very rouhg, and dies. If you press the gas, it dies. Almost acting like its not getting enough fuel. or like a spark plug wire was off. I checked the plug wires and they are good. I good use some good advise.
