I have a 1995 Ford Explorer, over 100,000 miles. 6 cyl. On a recent trip out of town I started having problems with it. Seems liken whenever I was going up hill the gas would cut off on it and the check engine light would come on. When it was tested it come up the mass air flow sensor so I replaced that. Then the o2 sensor came up and we replaced the front 2 and had the cats gutted. Als the fuel pump was replaced about 6 months ago and the fuel filter was replaced before i went on this trip. IT only seems to ave this problem when it gets warm. I was wondering what could be wrong the engine is still reading an o2 sensor and the mass air flow sensor. PLEASE help i want my car back. i had to leave it inVA and come back to AR. Thanks

I would also check for a leak on the throttle body or a leak on the vacuum hoses. That could be causing a lean condition and giving you those codes.
