My '95 F250 Diesel will randomly act like it's gonna stall when I'm driving (RPMs go way down, doesn't accelerate when I push the gas). If I cut it off and restart it, it drives fine for a while then does the same thing. Got the fuel system reworked a month ago for a similar problem, it's worked fine since then. Any ideas?

rough idle, stalling, loss of power. - CarGurus

I would focus on fuel delivery including fuel pressure. Any of the sensors would turn the check engine light on, but low fuel pressure would not. Fuel filter, problem with a line going to the tank, debris inside the tank blocking the pump, etc.

10 amp fuse labeled instrument cluster also protects idle sensor on diesel models

run the fault codes and check for MAF/VAF sensor , accelerator position or throttle position motor problems
check EVAP for venting problems

You could have a bad or intermittent fuel pump. Not a cheap thing to have.

An OBD 2 scanner can read fuel pressure on the drive to see if your fuel pressure drops off at odd times to confirm. It can also tell if there are transcient vacuum leaks at idle which the engines idle air control cant compensate for.

Do the plugs, wires and cap too.

Have you checked your fuel filter or fuel pump as these can cause your engine to to shut off, but there usually is some sort of warning, but not always.

I have the exact same problem. Let me know if you find out what it is. [email protected]
