PeachParts Mercedes-Benz Forum - ML 430 PO110 error

Need help with ML430 1999.

Engine starts from cold ok but dies after 10-14 minutes of running. original error codes PO170 and PO173 fuel trim malfunctions left and right bank.
Again engine would quit after 10-15 running - and would only start again after 20-30 minutes has elapsed or engine has cooled down .
All indications pointed to a mass flow meter problem. Purchased and installed new Bosch mass flow meter.
Same problem of shut down after 12 minutes running but new error code of PO110 "intake air temperature circuit malfunction". (No PO 170- PO173 error codes registered.)
thought I may have defective new mass flow meter, so I waited for the engine to quit (by itself) once this occurred, I put in the cold (original) mass flow meter and tried to start - Engine would not start. I have opened up the top cover of the air filter unit to let more air in from the edges - just in case filter was not letting in enoughair - despite air filter in good condition
Again engine starts and runs / drives well for the first 10-15 minutes then dies. I have to wait 20-30 minutes to restart.

Next morning started engine - it ran for 13 minutes then dies - got two error codes PO100 and PO110 - I ordered another replacement (2nd one) mass flow meter. ANY SUGGESTIONS?
