Truck stalls at stop signs and red lights

Yeah I have a hydroboost system and my scanner tool just came in from Amazon and I am downloading dashcommand as I'm replying to this. I did however just find an exhaust leak would that cause this

Oops. Well, nevermind the brake booster suggestion.

My'88 C3500 supposedly came with a 454 and has a vacuum booster, but yeah, a '99 is much more likely to have hydroboost.

you guys are approaching this totally wrong.

what you need to do is get some vinyl decals on the sides/front/back of the truck that simply reads...
"i identify as a cyclist"

this will let everyone know that red lights and stop signs don't apply to you

at least that's what it's like where i live!

I have a 99 k3500 5.7 v8 dually and the truck runs great everything is good on it. It idles fine, drives fine, everything. Only code I have is o2 scensor on bank 1. I had the p1345 but fixed it the past weekend in hopes it would fix my issue too. It only happens when it warms up and only when I'm in drive or reverse and hold the brakes to stop. Please just need to know where to start looking to fix this annoying issue. Tired of having to put my truck in neutral at lights.

I had similar problem when truck got into closed loop. Turned out to be worn distributor gear. Idled fine when cold or open loop.

Ever find the problem? My 92 1500/305 120k, behaves the same even after new tank/pump, ICM module, wires/ district cap!

He asked some questions, then vanished without telling us what happened. Hasn't been here since May.

My advice to you, is the same as my advice to him. Read post #7.

My 99 K3500 454 had that issue and it ended up being the front coolant temp sensor (ecu) located under the thermostat
