90 Ramcharger dying

I have a 90 Ramcharger, 5.9 L 4x4, approx 85,000 original miles. It runs great on acceleration and cruising speeds. The problem is after so many miles (~25 or more) when I decelerate to a stop or a turn the truck just dies, no hesitation, just dead. It will immediately restart. I have replaced the 4th gear solenoid for a tranny problem, spark plugs, PCV valve, water pump, all seal and gaskets (I know that most of these are unrelated to my problem, but wanted to let all know I have been "babying" the truck). The dealer cannot figure it out. I rode with the technician yesterday with the computer on and ofcourse the truck did not stall this time, but the oil light did flash as it does right before it dies. The dealer tech said the computer showed the idle and vacuum readings were not what they should be. He suggested the next step to change the MAP sensor and maybe the computer, but he can't guarantee that this will fix it. Chryslers tech BBS also does not have a problem as unique as this listed. I love this truck, it looks immaculate and runs great, but I cannot have it die everytime I stop or turn. One day it did it 12 times in an 8 mile stretch. Anybody have any ideas? One thing to note, is upon restart the truck seems to idle high. Thanks for any and all replies.

Re: 90 Ramcharger dying

This may sound crazy, but intitiate s computer test, check for the code of Autoshutdown relay, If this is the case check the
fuelpump harness and circuit , then check pickup in the tank and wiring in the tank(sending unit) . This problem Had me for awhile
and the symptoms were the same, stop at a traffic light the truck would die..When its dead check for fuel pressure....Maxt

Re: 90 Ramcharger dying

My 92 Dakota did the same thing. I can't remember if the dealership replaced the Throttle Position Sensor, or the Speed sensor on the tranny. I think it was the Speed sensor. I'll check my truck records and let you know for sure.
Good luck!
