97 metro code po113 HELP!

My 97 metro 1.3 auto check engine light came on and posted a PO113 CODE IAT HIGH VOLTAGE I replaced the sensor and checked the connections and the light went off.About 1 week later the car just dies after driving 25 minutes or so but starts right up like nothing happend so I replaced the coil and all the spark wires and cleared the code,same thing happens.It seems like the spark or fuel instantly shuts off at any speed please help me I cant figure this out!:banghead:
