2010 cobalt. Looses power and shuts down at 50 mph. Goes into low power mode. Cleaned MAF and throttle body already. Any way to fix.

Check fuel pressure. Fuel filter could b bad. Disconnect battery connections. Leave unhooked for 5 minutes, connect battery. Start car. Let idlle for 3 min. Turnoff car. Let sit for 3 min. Turn on car, drive it. It should reset everything. If still bad. Test tps. If u need new tps go to rockauto.com cheapest
