Just had headstuds done 5k miles ago. Replaced oil pressure switch 300 miles ago. And a couple days ago a ujoint in my driveshaft shattered so I've been driving in 4x4 with no rear driveshaft for a couple days cause I destroyed my driveshaft. But just got in my truck to head home from my girlfriends and the truck starts normally and runs fine in park at idle but as soon as I put it in gear, doesn't matter if it's reverse or a forward hear and I give it throttle it Boggs out and dies immediately. I checked all the ficm plugs and there all right, batteries were replaced 3 months ago, no trans issues at all, only mods are studs, egr delete, sct with innovative tuning, 4" straight pipe and a leveling kit on 35s. And help is much appreciated it's 2 am and in don't have any tools or light so I can't do much now
