Check for any codes, in your power train control module and your throttle module. Nay lights such as a Service Engine Soon Light or a Check Engine Light or a EPC or ETC light? If so, then you definitely have codes in those systems, that will help figure out what is wrong.
i forgot to mention that when car quits running we get no check engine lights ,warning nothing out of normal. just quits. it is in a shop right now getting out. thank-you for your response.
