Hope someone can help me on YT 175 problem

[yamaha 175]

I hope someone can help me. I own a YT 175 trimoto three wheeler. It will start but dies out when the engine gets hot. I was wondering if anyone could help me figure out what the problem is.

Sounds like the oil pump quit working and the motor is seizing up.I would start there,If not the head gasket.
