I have a 1983 Ford F-250 with a 460 Eng. and auto transmission. My
problem is I will be running down the road just fine and all of a
sudden the engine will start loosing power with some surging. Up until
yesterday it would stop doing it after a short period of time and then
run another few hundred miles before it would do it again. Yesterday
it did it but did stop until I pulled off the road and restarted the
engine. Before I pulled off the road thought I must have went 10
miles. Every time I tried to go faster I ended up going slower. When
I did finally pull over the engine immediately stopped. I did take a
quick look under the hood to see if I could see anything like maybe a
flooding problem but nothing. I got back in started it right up and
then proceeded to drive the remaining 75 miles home on the side roads
with no problems.
Now do I have something in the gas line doing it? Is it an electrical
problem ? I have two tanks and thus two fuel pumps and switching
between them made no difference. I did take the carburetor apart before
this last trip and looked for any dirt in it so at this time I am ruling
it out as the problem though I might have missed something.
Help, suggestions, comments?
Does this truck employ a TFI ignition? (I *think* 83 was the first
year...) There is an ongoing problem with TFI modules failing (even some class
action suits I believe) Typically the result is cutting out, hot start
failures, etc., but I suppose a lack of advance function is possible,
given the seeming 'flakiness' of the TFI. Perhaps a quick check with a
timing light is in order. No advance? Look at the related wiring (SPOUT
in particular) first.
If the truck does *not* utilize a TFI, pardon me for being a babbling

Had similar symptoms on a '73 LTD. Died in the left lane of US Route
80 during rush hour. Turned out to be the fuel filter that screwed
directly to the carb fuel intake. From what I was told that is not
uncommon with that type of filter on Fords. Mr. Moats makes good
points. I'd check the air and fuel filters first.
I did take the filter out and it had a little stuff in in. Also have
another filter before it that is also kind of a regulator that passes
the gas back to the tank which had more stuff in it than the filter on
the carb. Had a new air filter on before it did it so that was not the
problem. Drove it 40 miles last night and not problem but then I have
drive it a few hundred before it showed up again also so just hoping
that did it.
