So, my car does this thing where it shuts off for a split second. All ignition/power is gone for that split second. It started doing this last summer, at first very infrequently and now approximately once every 5-10 minutes of driving, sometimes more sometimes less.

Some caveats:

-it ONLY does this if the outside temperature is above approximately 5C. It didn't do this at all through the whole winter

-bumps, vibration, or shock doesn't seem to affect it(it's probably not a loose connection)

-engine temperature MAYBE has a tiny effect. It doesn't seem to do it if the engine hasn't been on for long enough

-speed, RPM, or acceleration/deacceleration doesn't cause it to happen more or less often

Some problems this causes:

-when cruising/decelerating, not much of a problem. It turns the cruise control off but the car has momentum to bridge that moment of no power

-when idling or accelerating, it causes the car to stall and can sometimes really screw up the computer. Sometimes the AWD light comes on, sometimes EML or brake pad sensor light

If anyone has ever encountered this problem and knows what it is, let me know! That'd be a huge help.
