I am facing an issue with MBIST, first time to occur, after triggering MBIST when the test reaches a specific gang, the one including PSPR1 once it tries to start testing the ECU resets, not that the test failed it can't even start the test for that SSH instance.

Are you using the iLLD's? Running the MBIST can be as simple as one line of code from the iLLD libraries:
IfxMtu_runMbistAll( mbistGangConfig );

If you're writing your own MBIST from scratch, you have to be very careful to avoid RAM access while the MTU is testing RAM. You should also make sure that a debugger is not accessing RAM through any memory windows or watch windows.
