Now what? Are y'all saying that fixing the RCM will get rid of this problem?
The P0410 problem will not cause this problem. Are you sure there are no other codes. The RCM can cause intermittent stop and go situations, but they do not fit your pattern, but getting the three common soldered connections resoldered would not hurt.
I am leaning toward fuel filter/fuel pump problems, the pressure regulator may be acting erratically, I'll check some more here. If I recall Valk had similar erratic behaviour.
Are the battery cables clean and tight?
