First let me apologize because I have never posted before and I hope Im doing this right. I have a ford e350 super duty van 5.4 v8 triton 240k , daily driver. 2 days ago while at a stop sign it just stalled, out of the blue. next I cannot get it to stay running in any gear, keeps stalling. towed it home. now when I go to start it the speedometer bounced all over heck, stalls in any gear. called a few places and nobody seems to have a clue as to what troubleshooting i can at least begin to see to figure it out. its a daily driver, and every day its not running is $$ out of my business. does anyone have any idea on what I should be looking for? at?

 

There are some things we need to know.
Did you just purchase fuel,Could it have some water in it?
There were some issues where there was a water intrusion problem with the plugs on the PCM. Check them for any corrosion.
