I have a jeep grand that will just die while driving. The jeep literally loses all power. It does not appear to matter if I am at highway speeds or stopped at a light, it will just shut off with no power. Sometimes it will restart within a few minutes-other times it's hours. It was throwing an error code of P0443 (EVAP system) and I had the purge solonoid replaced today. When leaving the repair shop it died two miles away. Any ideas?

TIA!

get the fuel pressure checked as it may be a failing fuel pump.

the code has no effect on your issue.

When it dies you need to be able to check for spark, injection pulse and fuel pressure, one of these will be causing the problem, when we know which we can diagnose further, i would be looking at loss of spark as a primary concern.

you need a fuel pressure gauge and hook it up to the port on the fuel rail on the motor.
