Troubleshoot DSC pump?

I've been plagued by this problem off and on for some time and no one can accurately troubleshoot this to definitively say what the problem is. It's really the only problem the car has but it's kind of a big one.

I was thinking maybe if I turn off the DSC from the dash button would this take the pump out of the loop? My thought is that if the problem disappears, voila that's what we need to look at.

In my case you can be driving along generally fairly low speed 25-35 mph. may or may not feel a slight shudder. Then instant limp mode. Pull over, remove key. wait 20 seconds and then fine again for a while.
