engine cuts off after 2-3 minutes of idleing.

I can not figure out what the hell is wrong with my friends 1991 240sx.It starts and idles great but after 2-3 minutes of idleing it shuts off without any hesitation or sputtering. (By the way its a KA24DE). I checked for vacuum leaks, injectors are working fine, I checked fuel pump and fuel filter. I am thinking that it might be electrical. If anyone has had the same problem and fixed it please help a bro out. Thanks for any help in advance.

u should start by tracing the ignition and electrical wires. my dads car had the exact same problem ( given its a plymouth). his ignition cables had corroded in the steering column. got new ones and it was fixed. ur best bet would be to get a multimeter and set it to the ohm or resistance setting and check around on the wires. if any of them say an infinite reading then the wires broke. could be something as simple as a bad ground point or spark plug wire. hope this helps. good luck

I checked the coolent temp sensor with it out of the engine and the ohms reading is 1.791 k ohms and the with the element under hot water (running hot water from the sink) and it reads .853 k ohms.

I just tried starting it and it started just fine but still died after 2 min of idling, then I tried restarting it and everything electrical went out. I could not even get my keys out until I disconnected the battery and then put jumper cables on the connections to get my key out. Before I got my key out I tried jump starting it and as soon as I put the cables on the battery post it tried starting itself. any ideas about the haunted car???lol

Could it be the crank angle sensor in the distributor? how do you check this sensor?
