Gages come on when water temp goes to 260

I have a 2005 GMC savana 3500 work van. sometime while i am driving all my gauge and speedometer and radion stop working randomly and will stop for a minute maybe 2 and then come back on. i cant seem to get an answer why?i drove 5 mile and it did it twice just today 7/10/2014.it just started 3 days ago.

Replaced belt

If I give just a little gas to it, it runs fine. no check engine light, but occasional ABS light comes on. When I get to five miles per hour or less, seems as if ABS is engaging

Good day, i had asked some questions about this problem before and since then i have change some parts.

I have it worked on by a gmc master tech. with over 16 years experience. He diagnose it and told me that it needed a tune up and he did it. parts change (5 new coil pack, 8 ac delco spark plug and wires). He flush the fuel system and take out the injectors and check them for the right psi.

Over $1,000 dollars later and the problem still exist.
The hesitation is not as much but it still happen. One minute it will fight to pick up speed then the next it drives fine.

ANY Suggestion?

I lend my uncle my truck and he fill it up with gas, after that it started driving really bad. It don't accelerate like how its supposed to, rmp going up but vehicle moving very slow. I change the spark plugs, fuel pump, and flushing out the fuel system but it still doing the same thing. While its hesitating the Choke light on the dash board keeps coming on.

PLEASE CAN ANYONE HELP ME RESOLVE THIS PROBLEM ASAP.
THANK YOU IN ADVANCE FOR YOUR REPLY.

Tried MAF sensor, upper intake gaskets (possible vaccum leak), IAC (had to change whole throttle body can't buy IAC alone). Unable to find any vaccum leaks.

I left my blinkers flashing while I worked, forgot about it, and now the battery is dead. I have a charger, but I am afraid to use it without instructions ... help!
