Hi, new to the form. I have 92 prelude with 90 F22a1, I have dumped hundreds trying to find a problem. It will run great for about 30 min then start to bog and miss when accelerating. When I shut it off and fire it right back up it runs fine again for about 10 min and start running like garbage. I have swapped ECU, main relay, Coil, distributor, fuel injector relay box, rebuilt entire fuel system. I did however buy used parts to try and save so money on endless guessing so I buying a bad part is possible. Any suggestions would be greatly appreciated.

Maybe you're picking up some trash from the fuel tank. I've had something similar happen in a car and it acted sorta like that running fine then crapping out till it got shut off then reappearing.

it’s possible. The car sat for 2 yrs before I got it and did the swap. I have had filter problems in the past do to the rust, ill pull the pump again and check the intake filter. In the past it gradually got worse and I did a pump and filter. This is more like a switch though and goes from great to having to coast off the road to shut off and re-start. Thank you

Drop the tank and clean it out, doesn't cost anything but time...
