change coils and see if stays on 4 first.

I had a similar issue on my previous VX. Found that the wiring harness that feeds the coils had issues when I moved it around while the engine was running. It went away when I pushed down on it... so I zip tied it to the rest of the nearby harness. Problem "remedied". Worked fine until I sold it about 3 yrs later.
