Car was driving fine then when I got on freeway car won't going faster than 25 mph
Im having the same problem did you ever find the solution , i was driving on the high way and it just stopped going fast and was hard to get it to go past 30 mph
Foot to the floor, go directly to a parts store, and get a free scan of the computer for the trouble codes and their description. Post them here, or have a mechanic start diagnosing what the codes tell him to check.
Good luck.

Sounds like the alternator is going bad and killing the battery.

The best way to know what is happening there is to drive a GMC dealer and get them to hook in the diagnostic tool and read the computer memory for present faults.

First, you need to have it scanned for codes, then you will know what to look for. Dont replace anymore unneeded parts until you get a trouble code. you will need a OBD1 scanner. You will only know the cost and cause when you find the problem.
