Why does my 1999 f150 lose all electrical power and engine dies.
My 1999 F150, auto, 4.6 V8 loses all electrical power and the engine dies. It starts up again but the same thing happens again later. This has been going on for about a month but recently it is happening more often. Died three time this morning. So far it seems to happen when slowing down like to stop. I have maintained this vehicle, it only has 116,000 miles and in good condition. Do you have any suggestions?
