heat can cause the cps to have issues
no it wont stop the engine from running

The fact that your tach moves means that the issue isn't the cps

You have a failing fuel pump. everything you describe is exactly what happens when it starts to fail. I know, just went through this 2 weeks ago. Sometimes it will work, some times it wont.

So that everyone doesn't have to ask every time, put your car info in your signature. 99 & earlier use 1 type of pump, 2000 & above use a different one. Replace it before it strands you somewhere. You haven't said if you checked for codes at any time and if any where shown. If you did before it started and there were no codes....then it is fuel pump.

If your tach moves....it isn't CPS
