HELP PLEASE! 03 Silverado problem

[ArcticwhiteC5]

Hey guys wondering if anyone has had this problem and can help me out. Just bought my 03 Silverado with 120k a few days ago and having an issue. The trucks runs and drives great, until today, and it has happened to me 3x today. While cruising along about 30-40 mph today the truck suddenly died out for no apparent reason, and left me coasting down the road. the gauges all dropped down and the readout said battery not charging. I put it in neutral and tried starting it on the fly and it would turn over and begin to startup but then die right out like it wasn't getting fuel. I pulled to the side of the road and tried starting it again in park and the same thing, tried starting but then died like starving for fuel. I shut off ignition and let it sit for 2-3 minutes and tried again and it fired right up and ran fine but has done it twice more today since then. Anyone else ever have this issue? I'm wondering if maybe it is something electrical with the fuel pump possibly? ANY IDEAS?????? Thanks in advance!

when the engine is running do you have a check engine light on? have you checked the battery cables both at the battery and the starter and the ground for tightness?

no check engine light on when running and no codes in the computer. battery terminals are tight I checked those, I will check the starter connection though haven't done that. I'll let you know how it goes thanks!

if you dont know the maintenance history of the vehicle change the fuel filter and check the air filter

air filter got changed yesterday so it's new. local parts store guy (not some autozone goon) looked my truck up for me and said fuel filter is non serviceable. so I'm assuming its just some screen part on the filter itself? anyways, the truck started running pretty poorly today, kept losing power and bucking and stalling out just running horrible and eventually the check engine light came on. I hooked it up to my scanner and it pulled a code for the crank position sensor, which makes pretty good sense to me. so I picked one up this evening and am going to try to change it out and see what happens.

guessing on which engine you have, 4.8? came up with inline fuel filter on autozone site

it's the 5.3L motor. I changed the crank position sensor yesterday and cleared the code out before starting it and it runs great now, no more problems. actually smoothed out the slight miss in the idle too it seems like. So problem solved and runs like a champ. Thanks for the input everyone I appreciate it. Hopefully you never have this problem but if you do you know what it is now.
