Why would a 1991 190E 2.6 engine bog down and almost die out and stutter when given gas from a stop?

It's possible the MAF (Mass Air Flow) sensor is not functioning properly. As you give it gas the MAF should open the throttle body and allow a proper mixture of air/gas. If one component is not working right then it is concievable that you could be "flooding" the engine enough for it to bog down, but once you start moving you escape a complete stall. There are many components that might be involved (O2 sensor, air temp sensor could be bad). For expert opinion check out the Rev! 190revolution.net
