Well, battery is probably ruled out then.

Do you have a code reader? Other thoughts are the usual things: fuel filter, fuel pump, even "bad gas". A good code reader is well worth it (generic reader can't read all the extended codes). On my iPhone, so I can't search, but there are some threads on readers if you search. Only other thoughts are to run new gas and see if it recurs; if so find a good indie shop to check it. Others may be able to offer more help/ideas.
