clean engine but wont run
 

I brought my 98 dodge diesel 5.9 24v into a custom shop to have the engine cleaned. When I went to pick up my truck the guy who did the work told me he thought I had an emissions leak. I said that's od my truck runs great. Then he started it as he was showing me the motor and after three minutes it stalled. I said that's never happend. Bottom line. They cleaned my motor and now it won't run. It will start run normal for a few minutes then stall. It will get up to about 30 after warming up along time then stall and I have to re start. They didn't presure treat the motor but did use water to spray off cleaning solution. I need to know did something get wet gonna have to dry it out what could it be?

Tell them to fix it:c:

x2 make them do it its there fault!
