I was driving the car down the highway for about 20 mins and then moved to the city streets (45 mph). After about 3 miles the car sputtered mildly and then shutdown while driving. It would not start back up until it sat for about 20 mins. Then it fired up and drove like normal with no warning lights or abnormalities. After about 10 more miles of stop and go at 45 mph it died pulling it my driveway. Then again it took about 15 to 20 mins to fired back up and run normal. The battery has tested strong. The car does sit and only gets driven about once a week if that. My best judgement leads me to believe its an electrical/computer issue, but I'm no mechanic. Any thoughts?

Hi Mustang42, Welcome to 2carpros and TY for the donation

Next time it refuses to start don't wait for nothing do below and comeback with some testing results.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing
