===========

These details will help.

Thanks.

I'd use a gage and check proper fuel pressure, key on engine off. My info says 48 psi.
How long since over-all tune up?

I once had a problem like this one, the car started but when i put in on drive the engine died.
This was because the engine moved when put in drive, and a ground to the injectors was lose, so just got it tight and problem fixed.

Start your engine and move the harness a bit if it dies there's a lose wire.

Hope this helps. Good luck..

Sounds like you have a restricted fuel filter that is causing your vehicle to start sputtering because it can't meet the engine's demand for fuel and then dies when fuel is depleted. After your vehicle stops running, fuel starts seeping by and you can start it again with ease hot or cold and you get the same results moments later if this sounds right replace your fuel filter.

Mopar 5W-30 is what the book will tell you. Any good name brand 5W-30 will work.

sounds like the reason it starts and idles fine at start up is your choke is functioning... as your vehicle warms up.. the choke starts to kick off... Inspect your throttle body and idle control motor.

If you out the top down, on the windshield side posts you will see a small drain tube on each side. When these cars age the sealant used around the drain tubes rends to get crushed and distorted and tends to cover these tubes not allowing the water to drain down the A posts. This causes the water to back up and run down the inside of the A post and under the dash and onto the floor. It's also possible that the window seals are in need of replacement or adjustment.

You're getting a condition known as "vapor lock" or hydrostatic lock. This happens when you run your fule lines too close to a heat source (exhaust, engine, etc). You can solve it by re-routing it away from those heat sopurces...this should help.
