Hi I've been having this problem with my 2006 Maxima SL lately hopefully you can help me figure it out I would greatly appreciate it thank you for your time

Ok my problem first started about 2 weeks ago when I was driving to California and my car out of nowhere just shut off,the motor was still running and I was able to still accelerate but when it shut off all of my interior lights went out including my stereo and speedometer but the gauges were still working and the only light that stood on was my SES light and my headlights(this happend at night) signal lights on headlights still work but no signal sound on inside and this all lasted for about 5 seconds on the freeway then all of sudden everything just turned back on and back to normal and this went on for about a week when I got home from California it would do it every other day

But Now my problem for the past 4 days now on top of that is it's been doing it every day and shifter is stuck and my brake lights are not working but rear lights will turn on tho I have to use shift lock to drive for now
