Ford Windstar (98) V6 3.0L power loss : While driving since a while suddenly the van begin to lose power. RPMs drops, speed come down slowly but could not increse power when trying to accelerate. Accelerating does nothing, the max RPM gets lower and lower as I drive. Shutting down the engine a few seconds/minutes then restarting, solves the problem temporarily. But a few minutes later problem starts again. Having this happen more often as the weather get hotter (>50-60 F). Also most of the time I could put car in N and rev up with no problem, excepts when I continue driving until RPM refuses go over 1500 and then in N problem remains.
ANY IDEADS??? Seems that it maybe some sort of sensor getting hot and causing the power band to drop. Tranny would not kick down to lower gear when trying to accelerate either during this problem.
