Need help not losing my chips when I have a big stack

[Proofrock]

Stars 11+rebuy 45k guaranteed earlier this evening. Hero is 3rd in chips with roughly 120 people remaining. Pot odds kept me in this. Help on all streets appreciated.

The only read I have is that MP2 minraises with a wide range of hands. Less than an orbit before he had minraised with 78s to 8000, then called another 20,000 allin from a shortstack.
