2010 Honda Element stalls while driving.

2010 Element, 147k miles, sputters on occasion while driving. Sometimes it dies while driving slowly, usually while turning. Very infrequent. I replaced the electrical side of the ignition switch, no change. I have intermittent CEL. Was able to get a code read while the light was on for Mass Air Flow scensor. I cleaned MAF and checked for leaks. Still stalling. Pulled fuel pump and strainer looks clean. Pump develops 60 psi when key is turned on. Should I replace MAF scensor or is that likely a secondary indication? Fuel pump? Fuel pump relay?
