This is a problem that just occured today. I was at a light and when i started to accelerate, the truck started to backfire and cut out under a load. Idles fine, bogs under quick acceleration. I know i need to get a fuel pressure test, but my local autozone closed for the night 20 minutes before i got there. Any ideas would be appreciated. Thanks

 

Might be a fuel volume problem, if the truck still starts, it probably is not a pressure problem, since the truck needs more pressure to start then run. But still get that pressure test, also check to make sure the MAF sensor is plugged in, and that the air tube from the MAF to the throttle body is not loose in any way.
