Dodge Repair: Stalling, speedometer, fuel gauge problems, dodge dealership, o2 sensors

Question
Hi Pete.

Took your advice, and we put in new O2 sensors ( there are 2 of them in this model Dodge), and we disconnected the battery to reset the computer ( more than once) and it is still stalling (just shuts off as if you've turned the ingnition off) if you just let in run while in park. It cranks right back up with no problem. This truck is gonna be the death of us! I know this is hard one to diagnose. Do you have any more suggestions? Any questions that we can answer that may help you diagnose? Thanks so much!-------------------------

We have a 98 Dode Ram 1500 (V-6)w/ only 15,000 miles. Here is the problem, which we cannot get diagnosed. We just want it fixed,as we have 4 years of payments on it! In the morning, if you just let it run (especially when cooler outside) it will stall. When driving, at about 40-50 mph,ALL AT ONE TIME THIS HAPPENS:  it feels like the engine is cutting out, speedometer jumps down about 10 mph, fuel gauge flucuates a little or all the way to the needle, and the check engine flashes for just a split second. Also, when the overdrive is off, it will actually come and stay in overdrive until you manually change it. And-- when you come to a stop at a red light, it stalls as if you have turned the engine off...have to crank it back up to get going.
We have had it to the Dodge dealership and other shops to be diagnosed, and NO error codes come up, even with the computer testing sytem that runs while the truck is driving. NO CODES AT ALL! The Dodge dealership put a new computer in....didn't fix the problem. We then had the cam sensor and the crank sensor replaced....didn't fix it. The problem actually started after we had the fuel pump replaced and a tune up (new plugs & wires, cap & rotor, throttle body cleaned), so not sure if any of this could have caused it or just a coincidence. Please help! No one has been able help us, and pray that you can give us your advice! Thank you so much!
