1998 Dodge Dakota

My truck has always ran like top and now it seems to hate me. It shuts off randomly, looses power and causes it to jolt. (Ex: You know when you're in a low gear, like first or second, and you hit the gas on and off it's like WV hydraulics?) And when it jolts it tends to back fire. No fun for me. Also there is a smell, but it's not like rotten eggs. It just smells like a nasty metallic. The catalytic converter isn't getting red or anything. The guys that I know that help me learn are in a split between the camshaft sensor, the crankshaft sensor, and the catalytic converter. This helps me out like none. Hope somebody can help me out.
