Upon reaching 50 mph or so after a hard acceleration up a hill or while carrying a heavy load, the engine will suddenly loose power, shake violently, and then cut off. Sometimes this problem can be averted by babying the gas and slowing down. If you push it past 60, though, it always dies, buts runs okay after a restart. This only happens from time to time in a random fashion, however. Runing the AC seems to make the problem worse, but it is not the cause. This has been going on for over a year.
I've switched out the coil, the spark plug wires, the mass air flow meter, and the alternator, to no avail. Engine diagnositic shows no codes. Tranny shows no codes.
Could it be a simple spark plug problem? Or, is it the ECU or maybe a fuel pressure problem? Perhaps a bad sensor that won't show a code? Any help would be great. Thanks a million. -BW

I have driven many cars toward and over the 150k miles mark, and haven't changed a filter. Maybe you got some gas at a station with a bunch of crap in the storage tanks.
