FORD F53 ENGINE ISSUES

Question

I have a 97 Fleetwood pace arrow vision. Ford F53 chassis. 460. 35,000 miles

For the first 10-20 miles is runs fine. Then it starts backfiring through the intake. I can't give it more than an 8th throttle or it starts bucking or bogs out and I can't go over 35 mph, and my fuel economy is non existent.

If I shut if off for a few minutes, it will run again for maybe 5 miles before doing in again, unless i wait hours for it to cool completely then I get the 10-20 miles.

Ive replaced the fuel pump and filters, the ignition control module, and coil. Set timing at 10° btdc with spout disconnected.

The tank is new, aluminum 100 gallon. And clean inside.

Im kinda lost so any help would be appreciated

sounds like you have covered most of the stuff, did you heck to make sure there are no fuel lines to close to the manifold? could be so maything, but at the same time not a lot.&nbsp; you did the coil and ICm, what about the wires and plugs?&nbsp; I would check the fuel lines, finish the tuneup with plugs and wires then see what happens as it starts getting way more involved after that&nbsp;
