Random car gremlin

Jinxx

Ok I know this will be almost impossible for anyone to answer I’m just hoping maybe someone has had this happen to them and point me in the right direction ....2017 370z nismo with boosted performance kit ...everything runs great ..no engine lights ..no misfire or poor performance engine idles fine ....however over the last few weeks I have noticed when I hit some rough bumps ..railroad tracks ...bumps that usaually hit both front tires at the same time ,my radio screen would go blank and stop playing for a few secs then come right back on ....now it seems to have advance to all power on the dash and car tuning off ....it is random and I can’t replicate it at will... car will start right back up . I can’t see anything obvious ...only thing I can think of is maybe the charge pipe that cuts over by the starter is against or hitting power wire and causing some grounding issue or maybe something behind the dash. I know it’s a very odd issue that can have a dozen causes but any info would be helpful .
