wife coming home one day,said it just cut off at stop light..but started right back up...next day about a mile from house died and nothing will not turn over...so i come home from work look at it find a blown fuel pump fuse replace and dis-battery...fires right up....50 miles later dies while idling on me....cycle key few times fires up nothing for 100 miles so i give it back....dies at her work .....ughhhhh....long story short its here now when its not going to crank i can tell because oil light isnt on.. when its on it fires up....only had this thing 6 mths bought it because it only had 67,000 and thought it would do good ...any sugg ...thanks guys so much

try the wiggle test on the wirring to and from the PDC.
also try wiggling the wires from the PCM
those codes arent the best to diagnose. they are instrument cluster codes
400.1 = improper power shutdown
100.6 = 'SBEC/DEC/MCM communication failure'
100.1 = 'loop-back failure'
sounds to me like theres a disconnect from power to the computer, if your not bald you maybe by the time you trace this one.
electrical gremlins like this are one of the most time consuming endeavours.
hope you got a good DVOM and lots of time, let me know if you require wiring diagrams
