Dodge B150 w/ 3.9L stalls at highway speeds

From : decorig u22516 uwe

Q: my 94 dodge b150 van about 150k with a 3.9l tbi stalls at highway speeds. no bucking coughing rough runing or any other warning symptom -- just dies at 60 mph. also dies at low speeds and sometimes also at idle -- same way. sometimes it will restart imediately sometimes i must wait two or three minutes before it will start. did complete tune-up air & gas filters wires plugs cap rotor egr valve. no codes set other than egr. drove it about 200 continous miles at 65/70 mph with no problem. next day it stalled four times within 30 miles at 65 mph doesnt appear to be weather related - stalls on both wet & dry days. anyone have any ideas here .

if you have the original cat it could be clogged. or a fuel pump .

it could be the pcm as well. try disconnecting the battery overnight to purge everything from it and see what happens. -- if at first you dont succeed youre not cut out for skydiving if you have the original cat it could be clogged. or a fuel pump .

i will be eagerly awaiting any and all replies. thank you bob m gentlemen - some additional progress information... taking your advise i suspected the battery and/or charge system. the battery being 3 years it was replaced once old was replaced this morning and the alternator seems to be pushing 14+ volts just fine. none the less i replaced the battery and once connected the underhood light came on bright and shiney. ok i said. after securing the cables i went inside and swithed on the ignition. nada! not even an odometer reading. out of frustration i then connected my jumper pack again and turned the starter switch again. this time it started. any other ideas as to where to look thanks bob anything that decreased the amperage to the starter and ignition system will cause these synmptoms. bad battery is the first place to look. but since your battery was only 3 years old and the synptoms conitue thats not it. check all your cables and connections. its common for a battery cable to corrode beneath the insulation especially the neg cable. try stripping back a few inches and see what it looks like. also check all your ground connections. take them apart clean and re-install. -- ..bob arrived 2006 fxdi red. 1997 hd fxdwg - turbocharged stolen 11/26/05 in denver 1hd1gel10vy3200010 co license j5822z 2001 dodge dakota qc 5.9/4x4/3.92 1966 mustang coupe - daily driver 1965 ffr cobra - 427w efi damn fast. .
