94 5.0 starts up and runs fine when cool for about 30-45 minutes when hot car will either cut off or or when car is turned off it will not crank or it will run for a few seconds and dies when it begins to idle. i have two trouble codes, 314 and 311. 314 AIR system inoperative during KOER ( bank number 1 with dual heated oxygen snesors) and 311 AIR system inoperative during KOER (bank number 2 with dual heated oxygen sensors). i do not know were to start fixing the problem so of anyone can help or have any idea please help me out.

Well good sir. Your fix in my opinion, which is absolutely worthless most of the time is very simple. You need to change your..............hmm.....uh............oxygen sensors?

Thats the first place i would start. I'm not sure if you have a tfi moduel on your distributor, but if you do, change that just for the hell of it.

that's what i was going to say...module or pick up

TFI modules are not on the distributor on the SN-95's and its less than likely to be the culprit... However it is a cheap place to start
