Automatic stalls while driving
I have a 1991 F250, 7.5 Automatic(i believe a E4OD) 4x4. I had the transmission rebuilt a year ago, I've recently replaced my TPS and gear position sensor.
When I hit a bump or it goes to shift it'll throw a check engine light and stall out. Sometimes it kicks right back on, others I have to roll off the road and pull the negative termial off the battery before it starts again.
I ran a the Key on test, got codes 21, 26 and 24. I ran the test with it running and got 77, 74, and 65.
I havent checked the codes when it stalls, mostly because I'm going up I-95 or I 70 in Maryland and I really want off the side of the road there. lol
Thanks for the help.

If it was only dieing after hitting a bump I would say check the wires under the EEC & fuel Pump relays sockets.
Unhooking the battery would only make the computer relearn the information sent from the sensors.

I went under the hood and checked all the connectors around the EEC, thinking it was something loose in there.
I'm certain its something computer related because of the reset temporarily solving the problems.

We have had computers on this site that would do that and when shut off for a while would let the engine restart and run again for a while and then do it again.
I think they have had bad caps in the computer. Some posters have replaced the caps for about $2.00 and that seemed to have fix it.

Just open it up and see what the caps look like. You might be able to fix it yourself.
Also re-read post #6 above as I have edited it.
