This may be a silly question, but I'm a firm believer in "start with the simple stuff first": have you checked the electrical pigtail connection at the tiller? Cleaned it thoroughly on both the male & female sides? A little rogue voltage can wreak all sorts of havoc. If the connection is good, maybe someone can provide normal specs so you can ohm out that wiring harness, just to make sure everything is solidly connected to where it needs to be.
If that's all good, I might lean toward an MP software flash from Prinoth? Certainly seems like this must be either electrical or electronic.
But do note that I'm not a mechanic. I've spent a lot of time around these machines, but more on the ops side.
