no preheat, but WIERD post heat!

so it was about 40 degrees a morning or two ago, thought for sure it was gonna preheat, but it didn't. Instead, it post heated, but not like it ever has before. For this one, the grid heaters came on after i started my truck (could tell cause the dim lights and voltage drop) but they stayed on for about a minute straight, then kicked off. Then they did it again, but it seemed for even longer this time, then kicked off again. Only did it twice, and that was it. Any takers? Relay problem, bad connection...bad pcm, or whatever it is?
