TRUCKS DOWN help info needed po251 and p1688 and more

I have a 1998 dodge cummins diesel, it idles ok and when the pedal is pushed it boggs bad. ive replace the lifter pump and the throttle position sensor. looks to be the price injector pump. odd thing is it keep coming back to life. so is that truely the problem. ive hered when the injector pump gone it gone. i can turn off the truck pull the key, get out a can still hear the lifter pump, pumping for a short time... and early on before i figure out i needed to replace my lifter pump the transmission shift from overdrive back and forth to drive. but only for about 100 miles ive put 1200 miles on it and then all of a sudden the funny shifting came back for a short time and then the bogging showed up for a while and then would quit not i cant get the bogging to stop unless it at idle but the idle is a little rough... please give me your input....
