[QUOTE="hal keiner, post: 797798, member: 66101"] I suggest installing a pressure gauge to see if the fuel line pressure drops below normal when the engine stalls. A pressure gauge test is a good way to positively confirm or eliminate poor fuel flow as a cause of stalling, and under what circumstances. I once had a vehicle that usually ran fine but would unexpectedly stall at times. I eventually determined that this was caused by a fuel pump that failed only when the outside air temperature was very high, the vehicle was parked on hot asphalt for a while, and I was at a high altitude in the mountains. Apparently the warmer than normal fuel temperature in the tank along with lower air pressure caused the fuel pump to temporarily fail until things cooled off. It took a pressure gauge to troubleshoot and confirm this unusual cause. [/QUOTE]
