03 lb7 died on decel

[squeaky3]

So i had a problem with my truck tonite. I was coming home from the girlfriends house, drove bout 10 miles at 60mph, get to town slow down for reduced speed limit, light turns red so i start come to a stop, as i slow down battery light comes on and dash says not charging, truck is running real rough and very low idle, put in neutral to rev it up and it puts and dies like it was out of fuel but has 1/2 tank. Pull over, shut key off and turn back on, truck starts fine and drives fine.

Pulled codes, p010 for MAF, p0571 for brake switch A circuit and p0621 forgenerator L-terminal circuit. Any ideas on what caused the truck to die before I look into it more tomorrow??

Sounds like possibly a bad alternator/batteries? Could have not been putting enough juice to run everything and just threw random codes... These trucks are weird if the electrical system is messed up.

I know my lb7 sometimes has the "battery not charging" and the light comes on too when I first start it. But then it goes away after a few secs, check the battery fuse first, it may be loose

thanks guys, i will check the fuses today

the MAF code im pretty sure is from the k&n filter that is on the truck that was just soaked in oil, i cleaned it off and didnt reoil it before i put it on, just havent cleaned the MAF yet

i just bought the truck last week so im still finding out all its little quirks
