Gauges go Crazy S-10 Blazer

I have a 95 S-10 Blazer and I have this elctrical problem or I think its electrical. The Gauges in my dash go crazy once I start to accelerate and go around 50mph then my truck wont start no more or it goes dead. Can anyone help?

i say your igntion switch may be failing.

Do you have to boost to start it again? How is your charging system, battery, alternator, connections.

Yeah evrything is good except my battery cables aren't AC Delco, I o have to boost it in order for it to start up again.
