2004 Volvo XC70 stalls suddenly, can’t find codes

car stalls suddenly after driving, low performance light came on after replacing altenator & new battery, sometimes hasn’t turned over & taken to 5 different shops cant find codes for whats wrond.

check for loose wires or battery cables and ground. seems like something is loose causing you to loose battery voltage. just like when disconnecting the battery you erase the stored codes.
