Diagnostic Test Code (DTC) P1193 is a manufacturer specific code (not listed in SAE J2012 as a standard generic fault code). Dodge lists the code definition as "Inlet AIr Temperature (IAT) Sensor Voltage High"
This code can have an affect on how your engine runs because the engine controller uses input from this sensor to adjust fuel and timing controls.
However, the symptoms you are describing do not sound like something that an IAT sensor would cause. It sounds more like your immobilizer is shutting things down (security system "thinks" somebody is trying to steal the vehicle)
I would recommend scanning your Body Control Module (BCM) and checking for active codes for your security/imobilizer system. It would probably also be wise to scan the REST of your computer network (ABS, IPC, etc.) to check for any fault codes there or network communications faults.
SOURCE: 1993 Dodge shadow died while being driven, won't restart
try the transmision you may have to replace it
SOURCE: 1990 dodge caravan starts then dies after 30 seconds.
cycle key, on,off,on,off,on & leave it on (not start) & count flashes from check engine light to see if getting any trouble codes. example: 2 flashes, pause, 2 more, is code 22. 3 flashes,pause & 3 more, is code 33, etc.. let us know what you get, if any. P.S. Code 55 - 5 flashes,pause 5 more, is end of message.
