Surging Battery Gauge and RPM

Last night I was cruising around a bit and as I stopped at a light with my foot on the brake, the battery gauge needle began to jump up and fall back down and as this happened the RPMs did a similar up and down fluctuation. Enough so that the truck was bucking and would have hit the car in front of me, had I not kept my foot on the brake.

This is on a '97 PSD with 100k miles.

The light went green, I drove off, and the problem hasn't resurfaced in the last 20 miles of driving. Any suggestions?

How far along driving were you? Like how many mins? Mine does the same thing, but not so bad on the RPMs while the glow plugs are still on.

Pretty far along. I drove it probably 30 minutes on the highway, then idled it for about 5 minutes, then drove for another 5 minutes when it happened.

I would think everything would have been good and hot by then. I thought maybe it was a battery connection, but seeing as how it hasn't reoccurred, I'm not sure.

Thats the plan for the weekend.

I got my first dose of trying to start the diesel in the cold (25 degrees) this morning without using the block heater. Damn my condo not having an outside power source. These things can be tempermental.

my truck has done the same thing, I have driven it (dureing summer months) for some distance (say 20 mins) down the road and stoped at a drive through or bank or red light and the truck started bucking for like 30 sec.s - 1 min. or more it was crazy,scared the **** out of me the first time... if anyone knows iam all ears.I had this idea it maybe the throttle positioning sensor but IDK, BTW I dont think my MAP sensor works at all that may have somthing to do with it
