I couldn't get the used distributor I was hopjng for.
$50 to eliminate another possible cause, but not fix the issue. Ordered and installed a Motorcraft TFI using the Artic Silver paste on the back and still getting the same issue.
Tried to pay more attention to what it is doing to see if it helps get any ideas. Same as before, about 5 mins after it gets to the middle of the temp guage, and I use more then approx. 1/8 throttle it starts cutting out while trying to accelerate. If I keep my foot into it, the best I can describe is a bog. Like when a dirt bike runs out of gas when you forget to turn on the fuel shutoff. If I release the pedal, it tries to accelerate cleanly when I get back down down the 1/8 throttle spot again. When it started cutting out I pulled over to see if I shut it off and restarted (thinking something blocking a fuel pick up would settle) but no luck. With how it acts, I am thinking it's a fuel issue, but don't know if it's electronic. Since the point it starts at is consistent, any chance it's still the TPS even though it tested ok? Or any other ideas? Also it cools back down while driving, but the issue remains until it sits.
