Hello!
I also had the secrets of jerky running of my Genesis MP15AC although i have had made the modification with the 3-point suspension as described in the linked thread:

The MP15 began irregular and jerky running and even stalling again. But this time i found there was no more a reliable electric connection between the the rotating axle stubs and the axle cup bearings. So in bridged them with a sort of wiper.
After the modification of the power pick ups no stalling anymore. I think this problem is cured.
Here is the same for Blue Box and RTR switchers:

But all is depending on each other:
- keep wheels clean
- keep all wheels permanent onto the railheads, no airtime allowed
- keep tracks clean
- convert dead frogs to livin ones
- eliminate dead pointblades, this is often a hidden problem which appears when dust and dirt collecting in the course of time between point blads and outer rails. So it is possible the point blades are el. dead.
