Question about 2003 Chevrolet Silverado 2500HD
My truck is a 05 chevy 2500hd durmax, This issue has only occurred after driving about 40 miles of interstate at 70 to eighty miles per hour. Once off interstate and coming to stop, the truck only has enough power to make 10 to 15 miles per hour tops with my foot to the floor. The truck smokes excessively during this loss of power, but after 10 to 15 seconds power is restored and all is back to normal. What could be happening?
Sometimes the problem is so simple you dont think of it. Check the transmission fluid level. If it is good then drop the transmission pan to see if the transmission filter did not drop off or the filter may be plugged. When was the last time you did a transmission flush? if not do that change the fluid and transmission filter this should be done every 50,000 KM

It sound`s like the excess fuel solinoid is sticking, take it out and give it a good clean...

1-timing on truck is ajusted by ecm,when u moved it u cause cam sensor code because it detected timing was off! 2-o2 sensors has the role of detecting air to fuel ratio coming out of exhaust,sends signal to ecm wich collects data from other sensors from that sets timing for best performance,if ecm detects something wrong in system data it will give engine code,that code will point at problem area,in your case o2 sensors probably detected lean fuel ratio that points to fuel system,blocked fuel filter or fuel pump faillure,elect,circuit damage,hope it helped!

Your going to have to get the ECM scanned, Auto Zone scan's for free and most garage now will scan for $10.00 to $15.00 since they all have the scanners now and need the business.
You could have a Vehicle Velocity Sensor (V V S) going bad or the wire harness it self. The V.V.S tells the ECM how fast the drive shaft is rotating and calculate's what gear it should be in relative with the engine speed and throttle position, and transmission fluid pressure.
Regardless you need the Blazer scanned to pin point why your transmission is shifting the way it is. Could be as simple as time for transmission oil and filter change for $125.00 or a loose wire harness.
Check your transmission fluid and try not to run the blazer to hard, to replace the transmission start at $1,900.00 for a rebuilt.
Good luck and hope this helps. Keep me posted

Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

Sounds to me like the battery post is breaking away from the internal plates. This is something that happens from time to time with a battery.
