Print stops exactly after the same time always

[pavankumar 0]

I've been new to u2 and learnt all bed level adjustment, temperature and speed settings, filament grinding and others. The prints come pretty perfect if they do and if not the first layer starts off perfect but it stops exactly after the same amount of time always. The filament is not grinded but the filament makes a weird shape when i abort and change material. What should i be adjusting to not face this issue?
