If you put it up on all 4's I'd suggest having someone inside the car as a safety measure to cut off the ignition in case the unlikely even it would fall off. What we're missing here is more observation "DURING" the problem time. If you can increase the amount of time you have to observe the problem perhaps something NEW will pop up or be seen.
I'm going to try getting my hands on an oscilloscope first. This would be a good test to do while using the oscilloscope.
