I have a very strange and very intermittent problem that is also very irritating. The last time it happened before today was four weeks ago.
Accelerating from a stop, not lugging the motor or anything other than normal, I lose electrical power for <1 second. Dash lights, head lights, clock, radio, everything. It all goes out and then comes back on. Truck then acts like nothing out of the ordinary happened.
The next time the motor is started, the clock is reset, seat belt chime is reset, and the truck idles at 2K no matter how warm it is. Every time you take it back out of gear, idle rises to 2K.
I turn the truck off, back on again, and the idle is down to 1.5K, but will go no lower until I put 10 miles on the clock, at which point everything returns to normal.

I have installed a Yaesu radio. It is wired directly via ring terminals to the battery clamp bolts and there are no shorts/exposed wire in the system. Installation was done to radio manual instructions. The truck also did this once before the radio was in.
The dealership says they can do nothing unless I can reproduce the problem for them (I can't).
I have an appt. with service saturday to fix (2nd try) the leaky diff drain seal (service manual spec torque, new gasket and plug, still leaks about 1qt/2 weeks).
