Anyone have a similar problem to this?
Ram 2001 1/ton 5.2. Got a new battery late last summer, over the weekend drained it by leaving the ignition on over night. Jump started and got it running but it won't stay started. Engine starts again volt meter shows 14.5, can keep it running with my foot on the accelerator but the minute I let up, it goes dead, but again it will start without a jump.
Ideas?

Dirty contacts @ battery.
Weak fuel pump or corrosion @ pump electrical connections.
Put a charger on it for a day or 2.
I can walk on water.......................but I do stagger a bit on alcohol.

Battery is toast. Take it in and get it tested or swap one from another vehicle to help diagnose

Will it stay running at idle with the vehicle that jump started it still connected? When you remove the jumpers, does it die?

There is no idle at this point.
Jumpers on it dies, jumpers off it dies. Ran it by keeping my foot on the accelerator, lifted and it dies.
Ran for awhile with jumpers on, then with jumpers off. Right now, there is enough juice to start it but dies when I let up.
I have been dealing with cars for 47 years, junkers to quality rides and always have been able to hobble home and/or fix just about everything. This is absolutely new to me, so looking for just about anything someone may have had happen to them.

I can't see where the battery is the problem. I'm thinking a computer problem that isn't setting the idle speed right. Or maybe a fuel pump problem that's not pumping enough gas to run it at that speed. How about a clogged fuel filter that's blocking the fuel?

I bought a battery charger on Amazon a while back and used it a few times and worked as advertised. "Schumacher SP3 3 Amp Automatic Battery extender /Maintainer"
please read the reviews and check for new products if you decide to buy one.

Put a battery in it. Had my '96 do the same thing. Turns out the battery had an open circuit internally and it wouldn't stay running without a jump box or another battery hooked up to it. No warning whatsoever, Shut the truck off at the metal recycling yard, trailer attached. Tried to start it 5 minutes later, and it was dead.

If he's able to jump it and keep it running by giving it gas my guess is it's running off the power the alternator is putting out, which is why at idle it dies.

Well guys, in playing around a bit in my mind, I am thinking Rock Chuck is onto it, the computer having a glich due to low voltage.
Guess a simple disconnect the negative for a few minutes and reattaching should/maybe answer the problem.
I shall strive to overcome and try that tonight. I shall return with an answer.

I had an O3 with the 4.7 that kinda acted similar. My auto tech replaced the cam shaft position sensor, and then a week later the crank shaft position sensor. Evidently it used the same code for both problems, or they normally just replaced both, its been several years so I dont remember some of the details.

Well as promised for all you folks on the edge of your seats, here is the report on this problem- Apparently as Rock Chuck surmised, the low voltage and jumping the battery caused a glich in the computer making the fuel pump to not pump at idle. The fix was, as I surmised in my last post, disconnected the battery for a minute then reconnected. Engine started and idled like a boss once again. Battery is still low but a good half hour drive should bring it to total life again. Thanks for all the input not only were they good ideas but also some reminders of things I need to get done. For those who stayed up all night for this report, you may now stand down.

Thanks for the followup. So it appears that anytime we run a battery down and nearly out, it might be a good idea to disconnect totally to drain the system, then start over from scratch?

Disconnect, charge and then reconnect and start your engine.... or do what I did.

Either way makes about the same sense.

I haven't tried the disconnect/drain, but my older Grand Cherokee is a bit*ch to jump and does the same thing.

You need to charge battery, Alt isn't a charger just a maintainer!!
