Truck dies while driving
I just picked up a 93 Ford ranger with a 3.0 v6. I bought it knowing it had issues but the guy was straight forward with what he thought was causing it (coil pack) so I went and got the new part and replaced it, seemed to have no problems when driving to work but on my way home it died while I was cruising at 60, couldn’t get into to bump start. It started back up after I let it sit for 10-15 mins. Any idea what could cause this? I’m new to rangers but know my way around cars. Just don’t know where to start with this. Only thing I could think of is a poor ground connection from the motor to body. But I’m not to sure if that would cause what is happening. All good on oil and coolant as well so I know it’s not overheating the motor.

Welcome to the forum
3.0l Ranger had distributor thru 1994, in 1995 they were distributorless and used a Coil Pack(3 coils in one package)
So your 1993 has a Distributor that uses TFI spark system and a single coil
The 3.0l in these years used a Remote mounted TFI module, usually mounted driver's side, front of engine bay on the rad support
Looks like this: https://easyautodiagnostics.com/imag.../image_1-E.jpg
The grey part is the module the fins are a heat sink
The TFI modules were a known issue, they would get warm and shut down then you would have to wait until they cooled down to get a restart
But, same applies to ignition coils, they can also get heat sensitive, so if you change that already then probably the TFI module
But.........................could also be a failing fuel pump in a 28 year old vehicle
But there is a test you can do
50/50 test, used since the 1890's on gasoline engines so time tested, lol
You will need to heat engine up and then turn it off
Try to restart, to confirm a no start
Remove the air plenum(air tube) from the intake, you can leave it off for the test
Spray fuel into the engine, Quick Start(ether), or gasoline
Try to start
If it starts and then dies you have spark but no fuel delivery
If it doesn't start then its a spark issue
