V70 Volvo Suddenly Stalls

10 yr old V70 with 100K miles. Generally running well and fully serviced. Suddenly stalls, generally at low speed, without warning. No codes in system and mechanics could not replicate problem. After stop, starts up again with no problem. Idles fine.

Cam or crank sensor failing. Fuel pump could also be suspect.

Sounds like maybe an intermittent fuel pump problem, either the relay or the pump itself. See the last post on this thread:

You might want to check if you’re eligible for a new fuel pump inder this recall:

The recall was not for stalling but for cracks in the fuel pumps. But a new pump might solve your problem anyway if it’s free.

Could also be a worn ignition switch, which can cause also cause stalling with no codes.
