Crankshaft/camshaft position sensor works, no spark

[PaulsM]

Hello. Why would VEMS turn off spark and maybe fuel injectors, at triggerlog record I can see crankshaft and camshaft sensor.
Drove home, everything fine, next morning car won`t start. Then, after a day it starts, then again nothing, but both triggers work.

Possible the sensor is acting up.
