New bake master cylinder makes truck die???

[GEHSRanger93]

I put on a new brake master cylinder today and just recently went to drive it around the block to see if everything was going good but when i start the truck it starts and dies, does that twice then finally starts up and it idols down at 1,000 rpms and 1,600 rpms back and forth not steady at all, then i try and drive. (manual by the way) and it starts going but then looses all power and dies the abs light is on also then after it tries to die the check engine light comes on and sometimes it dies completely and others i can save it before it dies but it still wont even make it up the street and i have work tomorrow ahh!!! Does anyone have any clue, i think it may be some sort of leak from the vacuum of the brake booster but cant find a leak....

Thats what I figured, is there any way to check the brake booster?

yes use a vacuum gun and see if it leaks vacuum. Or a lot of times it will make a hissing sound. Try to hold the break to the floor and see if it will start and run.
