blender crashing test play

Hi, I Imported a blender model it keeps crashing it when I play tested no idea why it has low poly count only 160, never had this problem before. But it just keeps crashing no idea why it does either it just wont run. Have other models in the scene that are way more complicated no problem used the same modeling technique for all models. No problem ever with any of them not sure whats going on but anyone else have this problem.
