Default Engine Shuts off randomly

Hello I have a 2000 Ranger with the 3.0 it's a 5 speed manual my truck has 207,XXX miles still runs strong but I'm trying to diagnose it it's got a bad throttle positioning sensor (TPS) the truck will seem to be running fairly well it's been idling right under 1k rpm but driving the truck will randomly just shut off radio and lights all stay on but engine will just stop running it dosent sound like it's a fuel issue bc it just completely stops no stutter or anything it just does my next guess would be coil pack but idk any help would be greatly appreciated thank you.

Unfortunately there's a long list of things that could be wrong and cause the engine to die. Bad ignition, coil, ecu, wiring, several sensors, etc etc etc. The DTC codes will help narrow it down.

That's a tough one, I'm not too familiar with the flex fuel systems. My gut tells me the fuel composition sensor would not be able to cause the engine to just die. Even if the sensor is stuck thinking your using E85 when your actually using pure gasoline the truck should just run extremely rich, and throw a bunch of other codes. Let me see if i can dig up the service manual for a 3.0 flex fuel truck.

I see that the original post is a couple of months old, but am wondering if this issue has been fixed? My daughter has the same truck with the same symptoms. Fuel pump and filter has been replaced, new coil pack and CPS, nothing has helped. The only way I can start the truck is to hold the pedal to the floor. It will start but run extremely poor for about 15-20 seconds and shut off. Any help with this would be greatly appreciated!!
