So the engine doesn't actually shut off it just loses power? You mentioned I think it sounds as if it's misfiring correct? I'd doubt you're losing voltage as I'd expect a severe "buck, backfire" as power were restored, I've seen this many times at work with intermitent power issues to various modules the veh. would act as though you cycled the ign.Did you mention you have a scope? If so this may help in diag. this issue, hopefully it has a "glitch" feature? The new crk. sensor is it the shielded type.... grounded to the block. I've seen many issues fixed mostly on the MSD digital units by installing the shielded type crk. sensor.
