2008 420 won’t start gear indactor light “-” flashing

I have a 2008 420 electric shift when its tilted about 10 degrees only on the right side it shuts down. the gear indictor light is flashing a constant " – " its a steady flash none stop. when the key is turned off then back on the FI doesn’t cycle and when you turn it over it just spins over. Once I level the quad out it runs like new. I Have changed the angle tilt sensor with no luck still same issues. Thank you
