HiCustomer Thank you for asking your question on JustAnswer. The other Experts and I are working on your answer. By the way, it would help us to know:
-Is the check engine light on?
-Have you tested for fault codes?

Thank you again for trusting us with your problem. Please reply as soon as possible so that we can finish answering your question.

the check engine light is not on. there are no on demand codes. it has some keep alive codes 14 18 and 63
Expert:  Scottdagoalie replied 5 years ago.
The injectors and fuel pump relay are controlled by the ECM , I would suspect that there may be a fault in the ECM. The codes are caused by loss of ignition signal.(14&18),and Throttle position sensor out of range (63 ) . Both of these codes will cause engine to cut out so I would start with these. First replace the TPS and inspect the Ignition TFI module for a fault.
