Probably that's a limp mode.
You can start with checking hidden menu, then most likely visit Volvo dealer or other garage.

I have a 93 Lexus ls 400 and it drives fine for awhile then out of the ordinary the check engine light pops on and the car all of a sudden losses power and won't acelerate any suggestions?

When the engine management system (EMS) detects a fault the car goes into "Limp Mode". This allows the car to be driven, but without any performance so you are not stuck at the roadside. EMS problems sometimes come up for no apparent reason, doesn't always mean there is an actual fault and it may just be a dodgy sensor. Unfortunately, you will have to get it checked out in this case because the car is virtually undriveable as it is.

Break failure code on volvo s40. also traction control, falure, car goes into limp mode, no idicators

If its the ABS warning, and traction control doesn't work, then it will be a fault with one of the sensor rings, or abs sensor. Your easiest method is to have a chat with local dealer, see if a tech can plug it in to diagnostics for a lunchtime cash in hand job. It will point you to which wheel has the problem.

My volvo s40 t5 2005 is suddenly losing power as if running out of petrol, then power kicks in again. computers at volvo pick nothing i never know when it is going to happen.

if computers arent picking anything up its not an electrical fault, sounds like your surging because of bad fuel or blocked injectors, run some fuel cleaner through the car and see if that makes a difference. fuel filters may need to be changed but try the cleaner first.

Volvo s40 engine management system light staying on.Is there any thing I can check to cure problem and is it safe to drive.

It is probably safe to drive, but is also likely to be running in 'limp-in' mode which, at minimum, will be burning more fuel. Take the car to Autozone or a similar business for a free scan of the computer. Take care of any problems that will be disclosed and then have them erase the light. Hope this helps!
