2005 GMC Savana 1500 electrical problems,acceleration

Need help with a 2005 Savana 1500 6cyl. I had a few times (4) since Sept 2013 that the antitheft system would prevent the truck from starting,it would start but the engine would cut off after a second.It hasn't happened since January. Three weeks ago, the heater blower would stop when I turned the engine off but then start blowing 2-3 seconds later,with the key out of the ignition, so I have to turn the knob to off to get it to stop. Two weeks ago, the battery guage needle started fluctuating wildly and then just quit working. Last week the dash lights went out,all the gauges are working except for the battery one.The radio display reads LOC . So at night the only lights on are the odometer and tho LOC on the radio. I can't even turn on the high beams. Another problem I have been having recently is when accelerating from stop, it's hard to accelerate,as if I had my foot on the brake.When it gets to speed everything is fine. Sometimes, I leave home and it has difficulty accelerating at every stop I do.Then I may stop at the store a few minutes,get back in the truck,drive away and everything is fine,accelerates like it's supposed to. What's going on and are all these problems related? Any help appreciated.

I have the same car. So far no problems with the Transmision. I had the Trans oil change out every 60 K Sure sounds like you need to get the Transmision checked. Is the fault light on. I have invested ina fault code reader sure is worth it. 
Good luck.  Vilmos

Guys, what you are experiencing is the car built warning system. When your engine light blinks it indicates a Major Problem has occurred or is occurring in the engine. When this occurs the cars goes into a "safe," mode which means all power is cut by at least half in an effort to save the car from more major damage. You can take your VW to any large chain autoparts store (autozone, advance, etc) a lot of them are offering a free engine diagnosis. Do this if possible to see where the problems maybe coming from and ways to fix them.

SOURCE: turn the key and nothing happens,no crank,no sound,no start

It seems that you have a loose wire, bad connector or perhaps the main computer itself that is causing a problem If the shop is not seeing any codes, or codes come and go, likely I'm right...but someone is going to have to actually do some intensive testing to find the real cause. You can likely get another computer from a local scrapyard far cheaper than what the dealer will charge you...as far as wiring, you need a good accurate schematic a good volt/ohmeter and lots of time to trace wiring. When checking connectors test the pin, then probe the wire going into the pin...often the problem is where a wire meets the backside of the pin, either corroding or breaking..This also applies to any modules such as the security system...what you see on the dash does not always tell you that connection to components is good. This is not a "fix, but rather, a direction to go in. (exactly what I"d need to do if I was there)
Right now, everything is suspect including fuel system, till you rule it out!!!

I had the same problem with my 2000 Sonata a couple of years ago. It was the crank sensor and once replaced, it solved the problem.
