Default 6.5 is acting like it's getting good fuel one minute n not another.

I have a 93 k3500 gmc 6.5. I drove it to my doc appointment and it ran fine. When I came out I started it and noticed by the sound it needed oil... no matter what I just can't get that under control.. ugh. All of a sudden it revved up then shut down. I tried restarting it but it wouldn't so I knew it had to be the oil. I walked over to the truck stop and got some, put it in the truck which it did need it and ever since then it's running as if it's bogging down then getting fuel. I can feel it as I'm driving it and it won't idle right anymore either. It has a new turbo as of 5 months ago and I always have a shop fix it. I just don't have the money for the shop anymore. Everytime I put it in there I'm charged over a grand and they lose bolts or don't tighten them or can't fix the problem without fixing other things first that wasn't the issue... and I've tried different shops. It's hard to find someone to work on my truck because it's extra heavy duty as it was a city work truck. This morn it started just fine, idled right then all of a sudden jumped around and shut down. Tried it again and the same thing happened.
