Hello,

This sounds like your fuel pump might be failing. When motors and electrical components start to fail, it usually happens when they warm up or get hot because when metal gets hot it expands and finishes off a failing component. Here is a generic guide explaining how to replace a fuel pump in the link below:

In the diagrams down below I have included the instructions from your vehicle's manufacturer on how to replace your vehicle's fuel pump. Please go through these guides and get back to us with how everything turns out.

Thanks,
Alex
