Help Needed with Hector

Playing as Maya at Level 65 on PC and I don’t last more than a few seconds in the fight with Hector. Is anyone at this level would be able to help me. Drop me a PM and perhaps we can arrange a session to get me through this mission. I’ve Tried a level 65 DPUH, Level 65 Plasma caster (incendiary) and Hector’s Paradise pistol, all with little or no effect.
Thanks in advance.
