I HAVE A 99 HONDA ACCORD V6 WITH 250K MILES. WHILE DRIVING AT 70MPH I WILL LOOSE POWER WHILE THE ENGINE IS STILL RUNNING AND THEN A COUPLE OF SECONDS, POWER IS BACK. THE PROBLEM IS INTERMITENT, HAPPEN EVERY NOW AN THEN, BUT DAYS OR WEEKS COULD GO BY WITHOUT IT HAPPENING AGAIN. COULD THIS BE A PROBLEM WITH THE MAIN RELAY?

Like Laurie Mack said. It is the inertia switch below the glove box. Here is some funny information. DON'T change the fuel pump first. Interesting fact: I bought the new inertia switch from Ford and the install instructions that came with it said to install the switch in the protected area to the right where the fuses are. It is like Ford knows it was a dumb place to put the inertia switch, but they won't let you know until after you buy a new one. I have read at least 20 other people on here that had the same problem I just had.

94-97 accord have common issue on key ignition. Key ignition seems to corroded. Solution take it apart clean or best way is to replace it. I know because I have done it to 94 accord 4 cylinders, 95 accord 6 cylinders and 97 accord 4 cylinders.

Horsecrap...go to an independent transmission dealer after you call the extended warranty folks and complain!
I can count the number of Honda transmissions that go bad before 300,000 miles on one hand.
Good Luck

I think your problem might be your fuel relay which is situated next to the fuse box in the engine compartment.
