You need to check distributor cap/wiring/spark plugs. when engine cold resistans at electric parts/connections is low. Then it warms up it increases and electric current goes down. Maybe you have bad connection somethere. Your car is equpped with digital motor electronics fuel (DME) injection. Here there is component location and diagnostic:

Also I would check fuel injectors itself (use injector cleaner), fuel filter (replace). If no help MAF sensor, trottle position sensor. There is good repair guide here:

Please kindly let me know if this info was usefull for you or you need more info.
Good Luck

2005 GMC Yukon Denali's computer shuts down after the truck warms up


sounds like a fuel problem, how many miles on vehicle? as a quick fix it would be worth using a fuel addative , you haven't said if petrol or diesel, if petrol get addative that covers the catalytic converter ,having a blocked exhaust system can cause engine to stall also get the OBD codes read as this will tell you what if any sensors/switch's are faulty

1999 Jeep Grand Cherokee Laredo 8Cyl4.7L When when driving over 50 miles per hour will lose all power whats wrong?


When you say it loses power, do you mean electrical power or engine power ?
You would need to look at the fuse boxes for a loss of electrical power, and use a scanner or code reader to check the computer for trouble codes for a loss of engine power.

Hesitation when accelerating, then the car loses power while driving then i have trouble starting the car after losing power.


you may need to get your injectors cleaned the fuel filter being changed is good the coil is another good one or your fuel pump could be weak and isnt giving the proper psi of fuel to the injectors so id say clean the injectors first if thats not it the fuel pump

Starts fine & stops in 3-5 minutes or driving in 1-3 miles.


Did you replaced your whole distributor or just the cap and the rotor? Have you check the pressure on you fuel line it could be your fuel pump.
