1985 Ford F-150 problems
A few days back I was driving on the interstate and after about 1.25 hours of driving I noticed my truck start to jump a little, kind of like it was about to run out of gas. When I exited about 10 minutes later I came to a stop at a light and the engine died. It did not run out of get because I had just filled it before I left. I tried to start it and it could not turn over. After a few minutes I managed to get it started but as soon as I put it into drive it died. So now I'm trying to figure out what the problem is. After it sits for a while it usually starts right up. It idles just fine but as soon as I shift to drive it struggles for a few feet and then sputters out. I've since replaced all the fuel pumps and all the distrubutor components and still the same thing occurs. If anyone has any suggestions I would greatly appreciate it. BTW, the engine is the original 1985 5.0L EFI.

Do you by chance have dual fuel tanks?
I had a similar problem and it turned out that the fuel selector valve was stuck partway between the tanks, and the in-tank pump was bad in one tank.
When the reservoir bowl at the base of the fuel selector valve was emptied, the engine was out of gas.
When it sat long enough the reservoir would be refilled.
We figured out that the valve was stuck after we replaced all three of the fuel pumps and the fuel filter.
