Hello, I've had issues in the winter that my engine would die shortly after starting. I figured out if I had to stop to just put the vehicle in neutral and it wouldn't stall. then it was fine when the weather warmed up until the other day I was driving about 70 and she just died. pulled it off the road and restarted - went just fine. i'm wondering if it's a crank/cam sensor? I bought both just incase.
A faulty engine coolant temperature will cause vechicle to stall out during climate changing.

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.
Good luck

since its a 1997 your jeep has EFI, electronic fuel injection. The most probable reason for your troubles would be the injectors or a problem with the computer controling them, not allowing enough gas to be pushed into the cylinder causing stalling or lack of power, also too much gas iin the cylinder can lead to back firing and stalling. This would also explain the reason it takes so long to start back up some times, all the excess gas in the cylinder is flooding the motor and u have to wait till the gas disipates till the engine will turn over.

The crankshaft position sensor was seriously problematic in those old jeeps. It's located towards the top of the bell housing slightly to the driver's side I think.

You need to check components again when the engine is hot and in no-start condition, otherwise, you will get bad info...obviously whichever part is doing this works fine cold. ones that react most to heat are crank pickup, ignition coil and the fuel pump.(bad ones get hot and bind up)

i failed to mention that sometimes sally shifts into 3rd on her own. the only way i can fix is by shutting the engine completely off. would an engine coolant do that?? thank you, you are most kind for helping me!!!
