While driving to the grocery store tonight , my "90 F-150 abruptly quit running. As far as electrical all seems well, engine will crank, lights (headlamps, instrument) work, no warning, running adequately one second, then dead. Quarter tank of gas. Had to leave it, too dark, no flashlight. When I look at it in the morning , is there something I should check that fails this way, fuse, fusible link, ignition brain, etc? Unemployed , hoping it's a bailing wire fix. Thanks in advance, Ken
