Rx7 shutting down by itself

Hi, recently on my rx7 single turbo fd i was accelerating on gear and suddenly the car shut down when still on gear (no rpm reading) then it started up alone while on gear (the rpm started reading again) ... This repeated itself the same day for 3-4x until when i was cruising and put it in neutral gear, it shut off and gave me a hard time to start, i sat a side on the street for about 5 mins and it started up again like never happened. Next day i tried going out again and was working normal until i made a 1st-3rd gear pull and when i put it in neutral shut off again, it didn't want to start from ignition and i started it on gear and the same as the previous event it worked like nothing ever happened.

​​​​​I have a haltech ecu 1500 and a fault popped up, im assuming the CAS (crank angle sensors) are failing somehow.... Any help is much appreciated thanks in advance. (See picture attached for fault) the wideband sensor fault was already happening prior this situation i already tackled that problem.
