Car:
1998 Nissan Altima
2.4 liters
4 cylinder
168K miles
While I am driving at seemingly random times, all the power will totally go off in my car for one or two seconds. If it stays off long enough, the engine shuts down. There seems to be nothing that ties these instances together. No strange sounds or anything else.
It may happen twice in one day, and not happen again for weeks.
In the past year, I have gotten a new battery, wires, new connectors for the battery, gotten my alternator tested and it seems to be ok.
What could the problem be?
