Turbo doesn’t run

Hello I get a 100th 10VTurbo Built.:87 added. With the there is also immediately a problem. If I start it the first time, he jumps immediately. Runs then about 10seconds and goes out. Start it then no more. If one waits half to three-quarters of an hour the same game. I hold it after the start on 2000 rpm he runs on until I go once from the gas. I start immediately after the start and I have to go nowhere from the gas runs he quite normal. If I drive about 15 minutes, he also goes no more. If then runs in the stand gas clean with 800 rpm. Can then also make it quiet. He then runs again quite normal. Since I don’t know about the turbo at all, I ask about it. For me looks as if he does not get gas. If he then stood longer, a small amount runs there, so that it is enough to start and run short.
