Thanks for all the ideas.
The car has 174000 on it, 3 injectors were replaced at
115K, and the car doesn't seem to be acting like it did
then. The car is running good at idle and while
accelerating until it cuts out.
The check engine light has not been on, so I assumed there
would be no codes, but I should check.
Seems like people are thinking electrical problem, so I'm
going to replace plugs and wires and see if that helps.
Otherwise I will likely check into the coils.
Thanks for the ideas.
