    have experienced the same problem, although not on a buick (pontiac). check the red box(main power supply) located in engine compartment. nut was loose causing poor connection which will kill engine. vehicle always started after tow, but showed no codes due to loss of main power. good luck.*** and I worked at a gm dealership
