2008 Volvo S60 cranks but won't start. Was driving and it started sputtering so I pulled over and as soon as I put it in Park it shut off. I can turn the key and it will sound like its going to start but won't. The car has 127xxx miles ran fine up until this point. I changed the plugs and coils seeing how that was the only code that was read. Once it shut off I waited for a minute and tried to start it back and then it read reduced power.
