Use obd port to scan for storred error codes might give a clue, might not either.
Intermittent faults are a pain.
If it does it again see if you can talk to ecu via obd port will tell you if can buss and ecu is getting power and working.
check any wiring ect you added as result of turbo install, like o2 , like maf extension cables, intector adapter cables .
