Lossing Power

I have a 98 E250 5.4 auto, every once in a while while driving down the highway the van will lose all power and drop down anywhere from 5-15 mph. the only way to fix it is let go of the gas and drop the speed and then hit the gas again and everything is normal. I have no idea what to start checking can someone please help me out Thanks.

Hey! Don't keep us in the dark!

There are many of us "silent" readers here who may have (or have had) similar problems and are interested in what you found to solve your problem.

Yer never alone here, even if we don't have a good or better answer.

So, how'd ya fix it?

I looked up the info and it said to try check your MAF sensor, PCV valve, vacuum leaks, or possible fuel filter. So i changed the fuel filter, air cleaner, pcv valve and cleaned the MAF sensor with some brake claner and unhooked the battery for 30 minutes and it cleared the codes and they havent been back on since.
