batch script only get 6 minuts execution time, and kan only run once

All i want is some way to make a delay in a workflow in 1½ hour.

Has made a batch script, to make a pause on 1½ hour:

timeout /t 5400

---

Pulseway runs the script i 6 minuts and "fail's" it - and then Pulseway won't use the scrip because it is "Script is in use"
