I thought I had that exact problem in my '93 Dakota (v8 - AT - 4wd) but in
my case the dealer proved it was something else entirely. Does it only
happen on hot days? On my truck the viscous fan locks up solid and pulls
tremendous ammounts of air through the rad when it's get's hot out. The roar
it made made me think of the same symptoms you describe. The dealer of
course couldn't find the problem until I took it in on a real hot (85+) day.
He took me for a test drive and when it happened he pulled over, slipped it
into park and held the engine roaring away at around 1500 rpm. In a couple
of minutes the engine cooled enough to unlock the fan and poof all was quiet
and we drove off. Another symptom you don't mention is how down on power it
seems when the fan's locked up. If I hadn't seen it I wouldn't have believed
it could be something so minor. There is a TSB on the problem.
