Question about Cars & Trucks
My Trailblazer is experiencing a loss of power. It seems like it is starving for gas. It will restart with no problem. When it is cold it will run fine for about five minutes and then the problem recurs. I have replaced the gas filter, but the problem persists. Any suggestions? Thanks. JDM

SOURCE: LOSS OF POWER
number of things
1 fuel injectors
2 worn throttle body
3 inside gas tank sending unit filter needs replaced
4 a/c compressor failing
5 replace air filter
6 depending on mileage of vehicle worn cam, bearings oil rings
7 oil and water mixing together (oil will look like chocolate milk on dipstick if this happens
8 not enough air from the electric fan in front of vehicle (hook constant power and a switch with power key off)
9 wrong fuel type (maybe you car requires premium)
10 alternator wareing out and makeing a slow drop in power
11 binding brakes or emergency brake line binding
12 worn sparks plugs wires and electrical unit that houses this
13 worn capacitor looks like a little tear can with power points on it
this is just basic diagnosing without being there to see the vehicle in person these are the things right off the top of my head that i can help diagnose right now
some of these things wont show on a diagnostic cause there more mechanical and sensors wear with mechanical
hope this helped you in your quest

I had a similar problem. It was my waterpump. I got lucky and was close to dealersip, so no major damage. Before it failed (about three months before) I noticed the decline in acceleration, dealership missed diagnosing the problem twice. They finally figured it out, when it failed and started clunking in the truck. Was an expensive fix but not as bad as destroying the motor.
Get the water pump checked asap. they changed an air line valve connector thing first which did not fix the problem.
Also, I had a fan belt changed just before the water pump failed. The new fan belt put too much pressure on the failing water pump, causing it to crash and burn about one week after the belt change.
Hope this helps you.
