is any part of your fuel line neoprene ? If yes, sometimes higher fuel pressure will collapse the neoprene hose and you will not get fuel to the carb. check this and let me know.
It's fuel injected
Check Crankshaft position sensor, also oil pressure Guage wire loom , if the wires are damaged in anyway this will cut off the fuel. let me know
The Rpm stop working an it don't have crank sensor
Yeah it probably does have a crank position sensor double check that go to the library if you don't have the manual and look it up its probably on the back of the engine or in the front of the engine I'm not sure and if that's not the problem it could be the throttle position sensor although I think it's more like the crank position sensor to be honest with you because you would have a running condition if the throttle sensor was bad usually but I think its a crankshaft position sensor and I'm sure it's on there just try to find it.
