I have a 2006 volvo xc90 that has been running great with the exception of today when my wife drove over a speed bump, the car shut off. No lights, no errors no nothing. The car started right up after this and has not stalled since. If I am being really sensitive, the car may be idling slightly, very slightly rough only when in gear. I am doubtful that is part of the problem but full disclosure. Does anyone have any ideas?

 

i woudl check the terminals on the battery to make sure they are tight and free of corrosion.
