Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** most common thing to fail like this is the fuel pump. It can often cause loss of pressure then start working again once it is cooled off without turning on check engine light. You can buy a fuel pressure tester from parts store for around $25 and next time problem happens connect the fuel pressure tester to see if pressure is lower then normal if so replace your fuel pump. Let me know if you have more questions, thanks.
