Losing power when hot
 
Just purchased a 4 cylinder 1990 Wrangler that had been sitting for a long time (several years). Driving it back home, it lost considerable amount of power after 1 hour of driving. Stopped and replaced the fuel filter, A lot of trash came out. Jeep ran fine for about 40 minutes, then lost power again. Replaced the fuel filter again, same results (losted power after 30 minutes) Stopped for gas, had lunch, Jeep ran fine again for about 30 minutes. Iím thinking that the problem it not trash in the fuel filter, but some electrical component that gets hot and causes the power loss. Any ideas what the problem could be, coil, Ignition Control Unit , catalytic converter, or some other component? Any help would be greatly appreciated. Thanks

I'd say the cat. converter. If the fuel filter is not clogged.

I'd second that motion.

Once the cat is blocked up or pretty much fallen apart inside, it's a huge restriction. Get it replaced or removed if legal in your area.

Critters can make home in funny places too. Intake systems, HVAC systems, exhaust systems......... They eat wiring and other plastic and rubber parts..........
