electrical problem on 1994 Volvo 960

When I am driving, all the dashboard lights come on and the car loses all power. I pull over and it starts right back up. Sometimes it does this two or three times a day and sometimes not at all. Any ideas? My mechanic can't figure out what is wrong. Everytime he drives it, it runs fine (of course).

Hi Debbie,
Sounds like the engine is stalling while you're driving. Has your mechanic check for diagnostic trouble codes? I would get these codes if there are any and post them here, then I can better assist you. I would also replace the fuel pump relay, they were problematic on these models and would cause this same problem.
yes, he comes up with fuel injection codes 113/115. What about the fuel pump itself, could that be the issue?
