Sporadic momentary power losses?

[911vet]

Thoughts on what this might be?

I suddenly loose power for a few seconds. It happens very sporadically and mostly when I'm in 4th or 5th at about 3000-4000 rpm.

Everything is fine, then power cuts out for a few seconds. My tach doesn't change during the event.

The first time it happened was a few seconds after I misshifted into 2nd gear going 50mph. I don't think I buried my tach into the red, but it was a pretty serious "oh sh**" moment! I got it into 3rd and was accelerating when I lost power. A minute later in 4th gear it did it again. I shut the car off and when I restarted and got into 5th gear, it did it again.

Since then it's happened a few more times.

What could I have done at that misshift to cause a sporadic problem? Or do you think it's a coincidence?

I can't figure out if it's a fuel or fire problem. But I'm thinking I should replace my fuel filter and DME and fuel pump relays. Would an 02 sensor do this?

Thanks.

Double check the battery connections. I did a high rpm shift on my '74 once and the power cut out. I thought the rpm's did it but I found out I had a loose wire on the positive terminal.
