Truck acting up!!!!

[2001Stroke]

So I was driving along at about 50 mph yesterday and all of a sudden my truck started cutting out. I let off the gas and when I pushed on it again it was worse and the SES light came on. I pulled over and turned it off and when I started it again the light was off and it ran fine. So when I got in it this morning I drove for about 30 minutes and everything was working fine. When I was almost home I punched it from about 45mph and after about three seconds it just died! I put it in neutral and it started back up and ran fine the rest of the way home. Then when I went to work tonight it didn't have near the power that it usaully does. It almost felt stock and I was getting about 10-15 less psi of boost than I usaully do. I don't know even know where to start looking. HELP PLEASE!!!!!! I am hoping it will make it until Friday and if I can't figure out what is wrong I guess I will take it to the shop. Thanks for any advice!!

Remove your LOSE chip and reinstall. Try taping it into place with some good tape.

As far as I know the CPS has never been replaced. I bought it with 36000 miles on it and I know I have never replaced it. I will try reinstalling my chip tonight before I do anything else. Thanks!

I have over 130,000 miles on it now. So I think it would be worth replacing, even if that it is not the problem.
