My truck quit running and I dont know why.
I have had no problems with it at all untill today, I pulled out into traffic shifted to 3rd and in the middle of accelerating it just died!? I have a TST PM3 with the R-46 remote and I noticed that the remote had died. Naturally I checked the fuse to the TST and it was good, the truck even turned over no problem. Well I noticed the ground on the drivers side battery was a little loose so I tightened it and the TST remote lit up again. I thought maybe it just ran out of fuel so I cracked 2 injectors and I got no fuel after spinning the engine over for a while. I had it towed but I dont know where else to look, I checked the fuses in the block on the drivers side dash and under the hood but everything looked good. Any ideas? I'm stumped.

no fuel at the injectors more than likey means IP. and that your lift pump either died at the same time or has been dead for awhile. or maybe as simple as a plugged filter. just my .02.

Its never done this before, I hope I just need to crack more than 2 injectors to bleed all the air out of the fuel system. I have loads of fuel coming out of the water bleeder on the filter housing and the truck had at least half a tank when it happened.

Instead of cranking on it, just bump the starter and the lift pump will run for 20 seconds or so. I've heard of this many times before, a hot box will do this sometimes when you let off quickly from hard acceleration. I've been fortunate enough not to have experienced this personally though.

Yup. It might not technically be vapor lock but that's what everyone calls it. Basically what happens is you go full throttle and then you back off suddenly and some how a vaccum gets created and sucks the fuel out of the injectors and injection pump and you gott go and crack lines and bleed the beast before it'll start again.

I had a feeling that's what it was. I just replaced mine. First one lasted 136k miles. Actually it was running fine when I replaced it but it was losing power and had no timing what so ever in it so it had to go.

It seems to be an HO/stick thing. I've never experienced no matter how hard I back off the throttle and I don't know anyone with an auto who has experienced it. Everyone I know with a stick has experienced it some time or another.

I've seen this happen to "autos" at the strip, and at dyno events, before. Back off real fast...the engine dies and won't start again.
Starting fluid does a good job of getting the engine up and running real fast in a situation like this. Just make sure the grid heaters aren't going to cycle "on" when you use starting fluid, though. If the engine is already warm the grid heaters stay "off".
