got my truck running a week or so ago.it will start right up fine when its cold but as soon as it warms up it will shut off.i thought since i hadnt installed the front o2s yet that was the problem well i just got it back from the exhaust shop.they put bungs in the crossover for the o2s, truck still wont run.when the truck is idling i'll get into the gas alil bit and even while im in the gas the truck will shut off almost like i turned the key off. all help will be greatly appreciated

thanks cody

 

I think that this is a case where scanning software would definitely be helpful...you say it shuts down when it gets hot...not sure what's common, but I wonder if the resistance is going up in one of the sensors as it heats up (like the crank sensor), or even the fuel pump. Have you checked for spark and fuel when the engine has stalled?
