I kind of miss my old Ford Maverick. Straight six. But the thing had a strange habit of suddenly dying for no apparent reason. And sometimes at an inopportune time...like when my wife was in labor and we were on the way to the hospital...
Commonest cause of that in petrol engine cars is oddly enough the easiest to fix ( if its the cause) and its the EARTH ( Negative in Americanese) lead from the battery to the body. They look normal but have oxidised inside to a point that sometimes they work and sometimes they dont.
