the intake air sensor will cause the mix to enrich until it chokes and will not start~ http://www.summitracing.com/parts/acf-213-243? seid=srese1&gclid=CPHSuovYx7sCFYlAMgod9BUAPQ

have someone check to see if the temp sensor for the computer is bad. The IAT sensor above doesn't have enough influence to make the engine die. Next things I'd suspect is the upstream o2 sensors, ign coil, or ign control module. All of which can be checked. O2's can be monitored by a scan tool and the ignition components can be tested at autozone.
