Momentary shut-offs while driving

[steven4mcg]

I mean like it goes totally off for a half a second at highway speeds. Also at times when I turn key off after stopping (seats won't retract atc.)
Even the radio settings need resetting. Happens about twice a day now. Any help? TIA

Is the car all stock?

sounds like you either have a bad battery cable or bad battery terminals. THis happened to me in my F150, it can be quite alarming. I actually tested the engine on a snap on machine and it told us to check the battery terminals. Sure enough, replacing them (5 bucks) eliminated the problem. Essentially, they don't conduct anymore and it cuts out the circuit.
